Author note: Before you read you should know Buffy becomes the Slayer when she is 13, everything else is pretty self explanatory but ask question if you need to.

Basically Buffy lived in England from when she was 7 till she was 12 living next to Harry Potter. This is a what if they were best friends and Buffy left but Harry never wrote to her. What does she do?

Chapter 1

Buffy in all her 7 years of being alive had never seen a boy look so terrified in her life. He had run out and around the backyard and she saw him couching behind the bush. He couldn't have been more than 4 years old and her heart went out to him. That is the only reason she could see that she went over to him and crouched next to him giving him her best reassuring smile and said "Hi I'm Buffy." He looked shocked for a second before whispering in the equally small voice "I'm Harry." She smiled and said "I turned 7 in January, my mom and dad moved us here last week." He looked at her quizzically probably because she just offered that information before he said "I turn 4 in July, My Aunt don't like me talking to strangers." She tilted her head and said "Not a stranger, already introduced myself. Want to be friends?"

And that was how she became friends with the great Harry Potter, of course she didn't know he was the great Harry Potter, he was just Harry. Even though they were 3 years apart in age it seemed he was older beyond his years and she was a constant in his life.

"Hello Mrs Dursley, Can Harry come out and play" Buffy said in her best grown up polite voice. Mrs Dursley looked like she was going to refuse so Buffy threw in her famous pout and said "Please, today's my birthday and Harry said he would teach me more English words?" Mrs Dursley of course fell for the pout like all grown ups did and a few minutes later Harry came bounding out, well as much as a nearly 5 year old could bound out. Buffy grabbed his hand and dragged him to her yard next door. She giggled and said "I didn't think she was going to let you come, do you know how many times I have to pull that face on her." Harry giggled before saying "Well, Happy Birthday Buffy here". He handed her his home made card and a flower and blushed bright red before saying "So we going to play cowboys and Indian princesses again?"

"Hello Mrs Dursley, I was wondering if I could give Harry his Birthday present, I won't stay for long, pretty please" She threw in her pout without waiting because by now she already knew that was the only thing letting her in. Mrs Dursley sighed before mumbling something about him being in his room before letting her in and going back to the kitchen. Buffy smiled brightly, scowled at Dudley who was sitting on the couch playing that stupid machine and walked over to the cupboard under the stairs. She knocked and Harry timidly opened the door, upon seeing it was Buffy he dragged her giggling form in and shut the door. He looked at the present in her hand excitingly and said "What did ya get me?" She smiled giving him her best grown up 9 year old smile and gave the now 6 year old the present. Harry unlike most children slowly piece by piece unwrapped the present and Buffy couldn't help but be impatient, if she could she would have been tapping her foot impatiently but instead choose to cross her arms. Harry slowly opened the box in shock at seeing not only a whole bunch of American sweets but also a train and a new t-shirt. Buffy laughed and said "The shirt is from mom, the candy from me and the train is from Dawn. I swear for a 2 year old she is the most annoying sister ever." Harry was so immersed that when he looked up with tears in his eyes, Buffy looked taken aback from the emotion she could see. He threw his arms around her and said "I love it. You're the bestest friend ever."
