best friends are always there for you
they love you
until they disappear
until they are gone forever
until they betray you
until they go behind your back and spread things about you that may or may not be true
until you make nice and do the exact same thing to them
and then you fell like crap and try not to make nice for real when all you get is punched in the face and then all your stuck with is defending your self while everyone around you is yelling "FIGHT,FIGHT,FIGHT!!!"
while all the teachers and trying to get through to stop it
this is what one bad thing can do to a friendship
