Why do we act that way?

When disoriented in an unknown city or town, which happen quite often... :) I welcome locals, even foreigners, helping find my way. So I find it normal to do the same when they visit known territories. Same goes with any kind of difficulty or challenge I could help others solving in my area of influence.

In my personal case, it came from a life choice I made when a teenager. Of course, there are influences and circumstances which eased my decision though it has to come from within. Relating positively to others, even unknown, is one of my way of being human.
