As I was reading an article, this phrase speaks volumes and reminds me once again to always think the best of others.

We will never know what the other person might be going through when we saw them this morning.
He/she may look grumpy or depressed
He/she may have push us by while walking
He/she may be in a rush and did not bother to say Hi

Who knows what they have gone through?

Giving the benefit of doubt
Believing in the best in people

be kinder than necessary- everyone you meet is fighting some kind of battle.
