People normally show their true colors after a few months.
Real friendships are the ones which are based on long-term
bond building. It's also based on understanding each
other.
There are some who leak their awful personalities after a few
months of playing nice and that's when you know that it's time to
let go of these friends.
However, there are also people who are really sincere friends -
these are the people who may sometimes have conflicting
personalities with you - but because of long-term bond building,
you have come to understand and accept them.
Anyone ever lost a friend to his or her partner, who requested
that your friend cease contact with you because your friend's
partner doesn't like you?
