I don't think most of us get near enough of that, in these hurried times where many people we encounter in a day are harried strangers. 

I read once that the trouble in men's hearts of late is because they are not smiled at often enough.

Sure works to make me feel content. I guess we all just want and need reassurance we're okay, we're visible, we're doing just fine, we're safe, we're valued. A smile, a loving look, says all of that. 

Versus all that honking, frowning, gesturing, and yelling we tend to get on the road and in grocery stores and malls and possibly at work. Down with honks and frowns! Up, up, with people.
