A/n - ok so I kind of fibbed a bit about it being Harry's party next but I got carried away writing this bit. I promise it'll be next

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Harry and Ginny sat outside on the front step watching the world go by. It was still early morning. Ginny had arrived earlier by floo and they were trying to think of something to do. Harry looked up to see the blonde girl from the park walking along the street again.

"Hi" she smiled as she got near to where they were sitting

"Hi" Harry replied as she stopped in front of him. Ginny smiled at her

"You're new around here aren't you" the girl said to Harry, more of a statement than a question.

"Well just visiting really" Harry replied "but we're moving in a few streets away soon"

"I'm Caitlin" she said holding out her hand "I live just down the road"

"Harry" he replied, shaking her hand "And this is my girlfriend Ginny" Ginny grinned, that was the first time Harry had called her his girlfriend.

"Where's the other boy?" Caitlin asked "Is he you're brother? You don't look alike"

"No" Harry laughed at this "We go to school together but he's staying here as well because his parents….erm" Harry wasn't quite sure how to continue

"Well they're away at the moment" Ginny interrupted. It was partly true, being in Azkaban could count as being away.

"Oh, right. So where is he then?" she asked again

"Draco? He's still asleep, I think" Harry said, noticing Caitlin looked a bit disappointed. "Is there anything to do around here?" Ginny asked Caitlin

"No not much really. It's boring most of the time. We generally just hang around the park, maybe you should come down later this evening"

"We can't, sorry, it's Harry's birthday and we're having a party"

"Hey, why don't you come" Harry suggested. "Bring a friend"

"Yeah that would be fun" Caitlin replied "Tonight did you say"

Harry nodded

"Anyway I better go my mum will be wondering where I've got to" she said "Say hi to…Draco was it"

"See you tonight" Harry called as Caitlin walked off down the street.

"Harry, what did you do that for?" Ginny asked him

"What?"

"Invite her to your party"

"Draco so fancies her and it'll be a great way to set him up"

"But she's a muggle"

"Yeah and"

"Well, what will she think when she walks into a room full of wizards and witches and loads of magical stuff"

"Merlin's beard. I never thought of that."

"We'd better go and tell Talitha" Ginny suggested as she stood up.

Inside they found Talitha in the living room reading a book

"Erm, Tali"

"What have you done? You've got guilt written all over your face" Talitha laughed

"Well, I kind of, accidentally, invited a muggle to my birthday party"

"How on earth did you manage that?" Talitha grinned

"We were talking to her outside and the party came up and I asked her before I thought about her being a muggle. It's that girl who keeps smiling at Draco"

"Oh great it gets better" Talitha laughed "Not only do you invite a muggle to a magical party but the one that caused you and Draco to hit each other" Ginny started laughing as well.

"Sorry" Harry said with a smile on his face

"So, it looks like we're spending the rest of the day de-magicing the house. Harry you go and get Draco up we need his help. Ginny make sure when you go home to get ready you tell your family that the dress code is muggle"

"Ok"

"Sirius, Moony!" Talitha yelled as she walked through to the kitchen. They both appeared at the back door, looking suspiciously like they'd been up to something. Talitha explained what was happening. They heard some shouting upstairs.

"Sounds like Harry just told Draco who he's invited" Ginny laughed. Harry and an unhappy Draco came down to the kitchen.

"I'll collect all the magical stuff and put it in the study, we can put a locking charm on the door and it'll all be out of the way" Remus suggested.

"I'll go and tell everyone to dress like muggles" Talitha added

"You three can come with me to the muggle shop to buy some muggle drinks and food." Sirius said "We can't really serve them Butterbeer. We'll get some beer and wine and some non-alcoholic stuff. You'll know what to get won't you Harry"

Harry nodded. Talitha pulled an envelope out of her bag and handed Harry some muggle money.

"I'll give it to you as you're probably more used to it than anyone" she told him. As they headed for the door Remus came walking past and went into the study with two brooms and an assortment of other wizard items floating behind him.

"Have you ever been in a muggle shop" Harry asked the others as they walked down the street

"I have a couple of times, dad took me" Ginny said. Harry laughed at the thought of Mr. Weasley in a muggle shop. He could imagine him asking what all sorts of everyday muggle objects were for.

"He always gets really confused with the money though" Ginny giggled.

"What about you Draco?" Harry asked

"No, never" Harry grinned to himself, this was going to be an interesting experience. Draco was about as clueless in the muggle world as he himself had been when he first went into the wizard world. Ginny knew quite a lot about muggles from her dad and Hermione but Sirius was almost as bad as Draco.

They reached the supermarket and Harry found a shopping trolley which he gave to Ginny to push. They walked slowly round the aisles adding items to the trolley. Sirius wanted to buy every kind of chocolate there was and took a keen interested in the packets of soccer cards. Harry hurried him past remembering what he had been like with the chocolate frog cards last Christmas. Ginny was having a great deal of trouble keeping the trolley in a straight line. Harry almost gave up when Draco and Sirius spent nearly ten minute discussing what batteries were for. Eventually they reached the check-out with enough drink to supply the muggle army as Sirius was convinced it wouldn't be as strong as magic alcohol.

"You'd better pay" Harry said to Sirius as he handed him the money "It'll look odd if I do" Sirius took the money and looked at it with a somewhat confused expression on his face. Their items were scanned through the till by an extremely bored looking teenage girl who didn't seem the slightest bit bothered that Sirius had no idea what he was doing. Harry wasn't sure she actually noticed him whispering to Sirius which notes to pass her.

By the time they got back to Remus' house Talitha had returned from passing the message around and between them she and Remus had muggle proofed the house.

"I think everything will be fine" Talitha told them "I helped Dung find some muggle clothes, Tonks is fine because her dad's muggle, Hermione's going to bring some muggle music"

"What about Hagrid" Sirius asked. Harry had forgotten about Hagrid, there was no way that he could be passed off as a muggle.

"He won't be coming" Talitha said "he's got to go away on 'order' business. He said he'll give you your present when he gets back"

"So as long as my dad doesn't get excited and start asking odd questions we'll be alright" Ginny said with a smile.

"And we'll have to hope that they'll be too polite to ask about Moody's eye and wooden leg" Remus laughed.
