Hi,
Is the tense correct for 'return' in the following sentence?:
After we exchanged phone numbers and agreed that she returns at 3 pm, the baby was lying comfortably in the office.
'Returns' suggests that she returns at 3pm everyday, eg she has a routine or schedule. I think that what you mean is
After we exchanged phone numbers and agreed that she would return at 3 pm, the baby was lying comfortably in the office.
The continuous tense for After we exchanged phone numbers . . . . the baby was lying comfortably in the office also seems to be wrong. I don't understand your meaning here. Do you perhaps mean 'while' rather than 'after'?
Best wishes, Clive
