> You pluck the fruit and pick it up; what of us?
Why don't you share or let us participate in your activity?/Why are you the only one to laugh at your joke? Usually one person climbs the tree or uses a long stick to knock down the fruit while an assistant shares the task and rewards by catching the falling fruit or picking it up. The saying may be applied to a person who prepares something to eat by himself, then eats it without sharing. It can apply also to a person who laughs at his own joke, leaving his audience unmoved.
