some friends, it seems like there's a communication barrier between you and them.
it gets so hard to talk to them.
you really still want to continue to be friends.
you do make an effort to initiate to talk to them
the replies you get make you wonder is it really worth it.
you get tired of those answers.
and yes, maybe you are less-important.
not that of a priority.
inevitable, as time goes by, you will get used to it and start to drift away.
