如果被人说sorry，我应该怎么回答？

sorry,That's all right! 中文就说“没关系”
thank you, You are willcome! 中文就说“不用客气”

回答sorry的就说:It doesn't matter.
回答thank you的就说:Not at all.

Sorry
-That's all right,
-It doesn't matter.
-You are all right.
-Not at all.

Thank you
-You are willcome.
-Not at all.
-(It's) my pleasure.

是老外说那你就回答英文,是中国人说,你就说汉语就好了,如果你再说英语就回觉得很怪

That's all right

You are willcome.

当然是 没关系 啦
