Laughter- what's the difference?

laughing with you--> you say a funny joke, or told a funny story, etc.

laughing at you--> you might of slipped on a banana peel [ I don't think that happens, but its an example lol ], or you might have something on your ass that you hadn't notice but everyone else did.

but sexy senior does a nice expiation too

Think back on what is it is that you said, if I seems like somthing a person would laugh at then probably "with you"

One other way is this:once the comment or action is said or done, imediatly look at their faces, if they're laughing immediatly then its "with you" if you notice a momentary pause* then its "at you"

*the momentary pause is caused by the first thought whcih is usualy them thinking "what the hell was that?"

When people laugh at you, you feel like crap and when people laugh with you, you feel like your having a good time
