learning experience

Sometimes a one little joke could hurt someone else's feeling. I've been faced with this problem quite a lot, because of cultural differences. I do think before I talk but I can't help with that type of stuff, because I'm so used to what I learned before, so sometimes I don't realize that some words or actions are "wrong" for someone else. When I make this mistake, of cause I will rethink my action but I also think as one of learning experiment, so I wouldn't make same mistake again.
