Why do little children randomly wave and smile at strangers?Takes me a few seconds to react, wave back each time because it is so unexpected

How did we end up in a world where receiving a wave and smile from little children is a noteworthy experience?

why don't adults? Positivity and friendliness are cheap positive externalities to provide, and are probably good signals as well.

Parents teach them to do it with people they know, & kids quickly figure out they can get a pleasing reaction out of strangers too.
