what happened to us?
we used to be so close.
people who didn't know us would say
aw..you two make a good couple
and we would laugh and say were just friends.
you were one of my best friends
but what happened?...
i know!
you started lying to me
and started hanging out with her again
you let her back into your life
and now she wants me out...
well boy for once she can finally have her way
because im not dealing with this anymore
call me when i can have my best friends back!
