Why did A use the simple past? The simple past is used when having a particular time in the past, I guess the time may be "what she just said", right ? But in this case, can I use the present perfect in A sentence, because the present perfect doesn't need a exact time.
A: Did you hear what she just said ?
B: No, I was not listening. I was thinking about something else.
Why was the tense of B's first sentence the simple present? Continuously, why did B use the past progressive? I think the simple past is alright for them, because we have the exact time "last night".
A: I'm sure you met Carol Jones at the party last night.
B: I don't remember her. What was she wearing ?
The grammar rules are: If you mention a particular time in the past, you can't use the present perfect, but you can use the past. If you don't mention a particular time in the past, you can use either the present perfect or the past. ________________ When referring to any event that is finished, you can use the past.
