I eat salt-- I'll grab a pinch of kosher salt and crunch away.
If I'm eating something with bones- like a lamb chop- I have to pick the bone clean. And if I'm eating a meal with someone who doesn't pick the bones clean, I will take the bones off their plate and finish them.
I can't sleep without a cover on. When I was a kid it was because I knew it would protect me from vampires, but now I just can't sleep unless I'm covered up. If it's a nap, it can be a little blanket, but if I'm going to sleep for the night I have to be covered up with a sheet and blanket. No vampires here, no sir.
