Well, I have two best friends, but they're my best girl friend and best guy friend so I'll just put both.
I met my best girl friend at field hockey tryouts in 7th grade. After a little while it we were just meant to be friends. Last year, I was at middle school and she was in high school, so we didn't get to see each other much. But this year we both go to the same school and are even in the same Spanish class. Yay!
I technically met my best guy friend at my 5th grade picnic, but I sat with him at the picnic with my ex-best friend (long story why we're not friends anymore) so yeah. I officially met him the next year in 6th grade and from there we've been friends ever since. He's not in any of my classes, but I still get to see him a lot.
