The key is to get to know people and trust them to be who they are. Instead, we trust people to be who we want them to be- and when they're not, we cry.

This is the problem with expectations.  Having presumptions for others will only set you up for disappointment.  I know this game far too well.  Just do you and be yourself.  Simple?  Never.  You may have high aspirations for yourself, but don't displace those unfair absolutes on someone else or you both, most likely, will end up with misty eyes.  It's far too hard to see when one person's judgement is clouded, let alone a pair.
