When you do something wrong, you should say "I'm sorry." Sometimes you accidentally hit a man look, out of courtesy, you should say "sorry" and "sorry", that is always around us. But I think the less "sorry" is good, because when you say sorry on behalf of you wrong, but when you do something wrong, you have to say I'm sorry. We should grasp every word "sorry" to make their lives little regret, I am sorry to know that sometimes that is of no use. Learn to say "thank you", people should frankly face the face of things, rather than to escape, say sorry.
