Sometimes I do that. Even if there’s no way for them to respond. If they can respond, I get a smile or nothing, so I think it’s generally a good thing to do.

My dad taught me early on to smile at people, because sometimes it’s the only smile they see that day, and how would I feel when I saw a smile after lots of sad faces?

That one stayed with me. I wish more of his wisdom sunk in, but that’s a good one.
