Hi,
In 'Grammar in context' by Hugh Gethin I found the information: 'Sometimes the conditional or past tense is 'shifted back' to the conditional perfect or past perfect to give a sentence with uniform tense use:
I would have come with you tomorrow if I hadn't already promised...
I would have accepted your invitation if I hadn't been going out tomorrow.
So, my question is: when exactly can we use it? What is this 'sometimes'?
I really need the answer. Thank you in advance!
