Useless

The worst part of being me is when i knew he's cheating on her.  but i couldn't do anything about it.
when i knew the story, but i have to pretend that i don't know.
to not being busybody in their relationship.
tapi rasa serba salah.  
because three of them were my friends.
and i have to take care of those three's heart.
i hope, none of anyone hearts' being hurt but, i know, there's must be someone hurting inside.
