★Saying“不好意思”when you step on others’ feet or cause delay to others. But“不好意思”seldom means sorry, this term applies to the situation that it is not subjectively your fault to cause the trouble. “不好意思”is the corresponding of “好意思吗”(do you feel right with that?). for instance, since it is very crowded in Chinese buses, he may ask“好意思吗” (do you feel right with that?) when you don’t say “不好意思”to the one whom you bumped into due to a sudden brake. This probably causes a fight so the term “不好意思”is to resolve a conflict.
