in the waiting line

When those random events happen to occur in our lives, in which we have absolutely no control over, how are we to react? Given, there's an idea called 'common sense', but unfortunately for modern science.. no one can control our emotions and irrational behavior. I couldn't help but wonder when it comes to dealing with relationships, or friendships.. how do we act when we don't really know how to behave?

Most of the time, friends are meant to stick up for one another when it comes to those random occurrences in ones lives, yet when it does come to a certain point when two friends who share very similar interests conflict, the end result is never good. It comes to blaming one another or being jealous. Both will debate and debate until one can prevail, however, none come out victorious. Instead, both find themselves pleading or wanting to let go of the reasoning for why they were fighting in the first place. So when it comes to forgiveness and letting go, is our behavior always to blame? And when that conflict ends, some resolutions are made to an extent, but what happens when each opposing party begins letting go of their walls, and start letting someone in. Is letting go really the best option.. and if not, where do we fall?
