Hi from Thaiand, most of us are mentally clam. We alway smile but for this things i dont know it's good or bad. Sometime when we face with something bad, we may smile. It just to help better from inside. but some foreign may not understand and seem we see all the things as triflining things.
we respect to the elde, all elder not only in our family. We can help other people although we dont know them.
By the way, every social have both bad and good guys. If you meet bad guy, may be because your bad lucky.
