Doesn't 'wouldn't have' refer to the past only? How would keeping 'then' at the end matter?
(If I removed the article 'the' before 'past' in the above sentence, would it be wrong? Why? I put it instinctively without any reason)
Also please answer my post titled 'Mixed Doubts' as well.
I'm sorry if it sounded like a demand. It's my bad not to add please to make it clear that's a request. Some don't like please, sir and the like. Otherwise, I'm inclined to make the answerer sure that its a request. Excuse me this time.
