You ever sit on a patch of carpet or grass so long that when you get up you have little indentations of the fibers or blades riddling your butt and the backs of your thighs?
After a minute or two the indentations start to itch so you scratch at them.
Pretty soon the itch becomes a soreness and maybe the next day you have little bruises where your fingertips dug in too hard.
All of that dumb pain for nothing, for refusing to move in the first place.
