some gestures or behaviors are strange to me in my country.

I think most gestures are good in my country. One of the things is to pat or touch someone when greeting or laughing. Also, when I meet someone accidentally, It\'s natural to say \" Hi,\" or \" Did you have a meal?\" and If someone whom I meet haven\'t eaten, many of them would say \"Let\'s have it togeter\" or \"Why didn\'t you have a meal ?\" in a sad tone. I think these are some kind of things to feel friendly each other. On the other hand, there is also a gesture which is to be removed. In Korea, when someone is looked at by other people, a man or woman doesn\'t like that. and someone who received someone\'s eye scowls inversely. I heard that in another country , if they make eye contact, they smile each other. I think it\'s very good custom or courtesy
