May I join you for dinner? =============================== we use Might when we are not sure about possibility, It might turn into a disaster! you might ask her for walk on beach! =============================== and we use "would", when we want to imagine something in our mind! if I had a chance more, I would tell her how much I loved ! =============================== Good LuCk

Can -> Can be about capability or permission. May -> Is about permission and is more softer/polite than "can". Can also be about possibility. Might -> Possibility.
