Question

Thank you, Writeacher. Can you please have a look at the following sentences?

1) I think in American English you can say: She said she was leaving the hotel the day after (instead of the following day).
2) He said he had lost his keys the night before.
3) I heard him play the piano (is it a mistake, is only "playing" possible?)
4) I saw him get into the car. (is "getting" a mistake?)

Answer 1

1. You'd need to indicate "the day after" what??
... the day after I last saw her.
... the day after the conference.
... the day after we had lunch together.
or what??

2. OK

3. play or playing -- either is fine.

4. get or getting -- either is fine.
