I friend of mine invites me to have dinner to his place and I ask him:
Me: What would you like me to bring?
My friend:Wine (should)/ (would)/ (will) be perfect.
Think that the sentences with "would" and "will" can be expanded like this:
If I brought wine, it would be perfect => This sentence is a hypothetical situation as in 2nd conditional sentence, so that this sentence sounds polite and indirect)
If I bring wine, it will be perfect => this sentence is kind of the 1st conditional sentence, so that the sentence sounds direct.
But with "should" I don't know if it is the 1st or 2 nd conditional sentence:
- If I bring/brought wine, it should be perfect.
