Nelson will frequently crack his knuckles or his neck or back or whatever. I can crack my wrist or fingers pretty much at will. Occasionally I can crack my neck or something as well. Sarah has noticed all this and has started trying to crack various parts of her body as well. This led to an amusing conversation last night that I thought I would share. :)
Sarah was sitting and felt the need to crack her ankle or something (I don't really remember what; it isn't important). She said, "I need to crack my body. But I don't want to crack it open. I better crack it while it's closed to stay safe!"
