I do them sometimes but I'm pretty shy, so unless someone looks like they actually need help, I probably won't offer. xD

I try to at least always be friendly and smile at people/wish them a good day though.

One thing that sticks out for me is Christmas two years ago. I took my grandma to church on Christmas Eve. The lady next to me was singing all the Christmas songs really nicely so I complimented her singing and she seemed really surprised but happy. Then after when I was leaving she grabbed my arm and thanked me and said it had made her Christmas. ;_;

That's kinda why I like Christmas. It seems easier to be nice and people won't think you're being weird or want something from them. XD
