Actually, I don't expect or desire "help" from strangers (other than in an emergency or disaster) so I don't feel the need to hand out help randomly either. I don't know that makes anyone a better or worse person. I'd prefer to cultivate family members, friends and neighbors. There is some enjoyment in helping people you like -- and there is the mutual indebtedness benefit as well -- they can help me when I need it to.
Anybody bugging and cajoling me every day is going to get very irritating very quickly. It would make me grummpy and rebelious.
Well, as it's said, there but for the grace of God go I. I don't expect help from the homeless man on my street, but I know I should try to help him. If I'm homeless someday, I hope somebody will find it in himself to help me.
