I have a question about can vs could in the IF clause.
If you could contact us directly, it would be helpful.
If you can contact us directly, it will be helpful.
Which one do you think is better?
I think since this situation is not impossible, the second one would be correct, but all of my American friends chose the first one because it’s more polite.
I know could/ would are more polite than can/ will, but because of “if”, I think the first may sound unreal as “if I were a bird, I would...”.
Could you please explain this?
