我想知道英语"对不起","不用谢","没关系"的所有说法(要分类列出来哦!)

对不起 ：
(I am) sorry.
(I am) sorry to trouble you.
Excuse me.
Pardon.
I beg your pardon.
不用谢：
It's my pleasure.
You are welcome.
Don't mention it.
My pleasure.
That's OK.
That's all right.
没关系：
Not at all.
That's all right.
Never mind.
Forget （about） it.
That's OK.
It doesn't matter.
