I was always moving or switching schools.

Switching schools doesn't affect _____ and mine's friendship :** We text, call & chat ^^
We've been best friends since we were 4 and now, we're 13

Unfortunately noooo.

I am still acquaintances with some people after 7 years, but no longer really friends.

I've been best friends with someone since we were 3, we're now 18 but we are drifting apart because of her horrible boyfriend. =(
(Not being bias as I don't actually know anyone who likes him because of his actions, he's just plain manipulative and awful)
^ Life story there. O_O

be nice to your bros and the friendship will stay...
that's all i a can say
