i don't get people sometimes.

i just don't get people sometimes. why can't people just own up to it when they know they are wrong????  cuz its just so frustrating to know that you didn't do anything wrong that the other person was so in the wrong!   i am at the point now where i am starting to just give up on people all together! i really am cuz this is just so stupid its not even funny. im just so fired up right now im so annoyed. so the only thing i can do is just to not to to this person anymore if she is not going to own up to what she knows she did wrong!!!    this time it wasn't my mentor friend, before it was my mentor friend but now its someone else.  will this ever end???  why is it that with everyone i come across everyone thinks they can just walk all over me. well its stops now!!!!!!!!!!!
