Good morning guys, glad to be here once again.
Treating people right and been expectant of same is really not ideal, reasons

1. You did be disappointed by not having the same measures returned to you, that's if you even happen to get back.
2. When what you expected is not forth coming you might probably decide never to do good again, for people will definitely hurt u at one point or the other in life.
   3.like a saying goes, the man who never expected anything from anyone can never be disappointed so do good and God will bring good your way.
