we were talking about a very special situation: a car accident.

or maybe other accidents. Those things are not common to us. Maybe once every 1, 2, 10 years?

Any way i was told do not be too quick to say "sorry" in any situation. It may be used to against you and then you will feel really "sorry". Maybe that is not a good advice. When I try to oberve native speakers around me, i found that it is really true, especially for the ones at high level positions. maybe my observation is wrong.

Do not want to convince anybody here; just want to share my opinion.
