Speakers tend to use 'can' and 'may' synonymously:
Can I come in? or May I come in?
But, the traditional use is as follows:
can = ability
may = polite request
Can I come in? Is it possible for me to enter? Is the door locked?
May I come in? May I have your permission to enter?
Pat: Can I borrow your pencil?
Sam: I dunno. Can you? Are you able to? (joke) :D
