The other day a Thai man was walking along with a bunch of Lamyai, a Thai fruit. He offered me some. (and NOT in a "hey, little girl, want some CANDY?" way, either.)
Then today, one of the red pick-up taxi drivers offered me a ride, free of charge. They usually honk at every foreigner to get them as customers, so I was really surprised by this!
Also, if you ever fall down or have some kind of accident, people will run to help you. It's a very nice feeling.
