I dunno, I laugh at the worst times. I find I use humor to hide emotions
one of my friend's got cut off by a vehicle while on his motorcycle, it clipped his front tire and he got in a terrible wreck
the first visit to him in the hospital after he came out of his coma I told him "That's the last time I hire a hitman off craigslist because they fucking suck at their job"
we both both laughed pretty hard at that one
Then his brother quipped in saying "no he's actually a super villain who attempted to knock the Earth off its Axis using his head"
