APOLOGIZE, EXCUSE ONESELF
If you apologize to someone, you say that you are sorry for doing something that they disapprove of, that upsets them, or that causes them trouble.
1. He apologized for interrupting her and quickly left.
2. Indeed not more than a week after her terrible accusations she apologized to Michael for what she had said.
3. ‘If I hurt you, I’m sorry.’ — ‘Don’t apologize.’
If you excuse yourself, you give reasons to justify something that you have done and that other people might disapprove of. These reasons are often not very good ones.
