Dear Native English-speaking teachers,
Would you please tell me which of the following two sentences is incorrect:
1) She was angry with him about keeing her waiting too long.
2) She was angry with him for keeing her waiting too long.
I really don't know because both sound correct to me. But I saw the answer in a text sheet showing only the first sentence is correct and the second sentence is incorrect. I have been confused.
Thank you in advance.
