-The Next Day-

Theresa apperated to Grimmauld Place.

"Morning, Dad," she said, hugging him.

"Morning," Sirius smiled," You wanna go wake Harry up?"

"Okay!" she said, cheerfully.

As she disappeared upstairs, Sirius smirked.

"Happy Birthday, Harry," he said.

Theresa walked into Harry's room. He was curled up on the bed. Theresa snuck up to his bed. She stopped when she saw his face. She grinned slightly, brushing back some of his bangs. She let her fingers pass over his cheek to his jaw. She then leaned in close to his face and..

"WAKE UP, HARRY!!" she shouted.

Harry shot up and fell off the bed. Theresa laughed.

"Morning, Harry," she said, kneeling beside him.

He scowled at her.

"Morning," he said, harshly.

He rubbed his side, where he had landed on the floor. He saw Theresa's hand replace his. He looked at her surprised, but didn't say anything.

"You might want to get dressed," she said.

Harry nodded and got up. Theresa walked to the door to go downstairs.

"Oh, and Harry," she said.

He looked at her.

"Happy Birthday!"

Harry smiled.

"Thanks," he said.

She winked ath him and headed downstairs.

-10 Minutes later-

Harry walked into the kitchen to find Sirius and Theresa waiting for him. He went and sat next to Theresa.

"Hey, Harry, I was thinking. Would you like to go around London with me today?" she asked.

"Um...sure," Harry shrugged, trying to hold down his joy.

"Okay," she beamed," First, eat your breakfast."

Harry downed that quickly.

"Okay then, lets go," Theresa said.

"You two be careful," Sirius said.

"We will!" they said.

Just before Harry walked out of the kitchen, Sirius grabbed him.

"Make sure she stays safe, or else..."

"Don't worry, Sirius," Harry said," She'll be fine, I'll take good care of her."

Sirius sighed as Harry left.

"Okay...I'll trust you," Sirius said.

-In London-

The two went to a bunch of muggle stores. They even went to see a movie. They spent hours in London. When it got dark, they went to Theresa's apartment.

"Its so small," Harry said, looking around.

"Its fine enough for me," Theresa said, making tea with her wand," Its cool in the summer and cozy in the winter."

"You could move in with me and Sirius," said Harry, timidly," The house is probably yours, actually."

"Harry, its fine," she laughed, making cups appear," I don't mind living here."

They drank their tea in silence. Harry racked his brain for something...ANYTHING...to say.

"Um...thank you," he said," For for going around London with me for my birthday."

"Its no big. Kinda lame gift," Theresa said, bringing her finger around the rim of her cup.

Harry smiled.

"Well, to me its not," he said.

Theresa smiled. They both jumped when they heard a clap of thunder.

"Oh...great," Theresa muttered," I guess you should be back to the house."

"And leave you alone in this empty apartment? I don't think so," Harry answered.

"Harry, I'll be-" she started.

"I'm staying no matter what you say," Harry said, stubbornly.

Theresa sighed.

"Alright," she said.

She cleaned the dishes magically and she and Harry sat on the couch. The two just looked around occasionally, glancing at one another. Once, they caught each other's eyes.

"Theresa, I don't know if anyone has told you, but you have pretty eyes," Harry said, taking off her glasses.(If you didn't know, she has them.)

Theresa blushed.

"Thanks," she said.

Harry grinned and gave her ber glasses back. They heard another crash of thunder.

"Harry, I'm glad you stayed," Theresa said," I'm really not that fond of storms."

She moved closer to Harry and lay her head on his shoulder. Harry hesitantly put his arm around her shoulders.

"Do you mind spending the night?" Theresa asked, drowsily.

"Not at all," he said.

They both lay on the couch. Theresa rest her head on Harry's chest and he wrapped his arms around her. After awhile, Theresa'a breathing changed to show she was asleep. Harry kissed the top of her head gently.

"Sweet dreams," he said.
