What does friend mean

Why do they call them friends
If they end up
hurting you
in the end
why do they pretend
to listen
when there not even listening
in the first place
Why pretend
to like me
when all you do is laugh
and talk about me
i don\'t understand
what the word friend
means
does it mean
to be there for each other
or does it mean
to talk about each other
behind our
backs
