I have a question about 'never mind' and sth.
Q1. Is 'never mind' used right in the situation 1? If not, would tell me what A could say?
Situation 1
A : Would you help me with this homework now?
B : I'm busy now. I'll do later. (But it seems that B's work is not important enough to refuse A)
Few hours later.
B : What's your homework? Let me help you.
A : ( *Never mind! ) (A was disappointed and angry at B's inconsideration. So A DOESN'T WANT B's help anymore.)
Q2. Would you tell me what B in the situation 2 probably says?
Situation 2
A : I don't know what I did wrong?
B : Really?
A : No! I don't! Don't blame me because of your fault.
But later, A realize that it was his fault and try to apologize to B.
A : I'm sorry.
B : ( ? ) ( B is still angry at A, and DOESN'T WANT to accept A's apology now.)
