My friend Henry would laugh kinda like that "Hull hull hull hull". Never heard him cry so I'm not sure. Usually a laugh is more like "ha ha ha", "he he he", etc. and crying is kinda more like "hoo hoo" or "a-hoo.. a-hoo..". It all depends where one positions their tongue in their mouth when doing such a thing.
I don't have a full laugh, never did. I usually snicker or make a wheezy sound kinda like Mutley "hheeheehheehheee". I don't cry cause I'm a man and men don't cry LOL. But when I do cry I keep it to myself. Very private thing, that is.
