emotional work

A friend's quote, "we are all working on something (about ourselves)",informed my whole emotional being. I need to reflect on that quote more often to be gentle and accepting of people's behavior.

My judgement is in the form of questioning.. why are they like that? who's says things like that? what am I doing to advance her/his mood?

The universal answer could be that they are human and they could be working through a particular emotional assignment.
