you make fun of me at school and infront of people just to act

you make fun of me at school and infront of people just to act cool. but when their not around your a completely differnt person. when they're not around you say things like i've got your back and you got mine. at school i always defended you when people talked behind your back but then i found out people were talking about me behind my back and you were talking about me to. so now im done. you "may have my back" but i know for sure i dont have yours anymore.
