I'd always been afraid of sick people, and so had my mother. It wasn't that we feared catching their brain aneurysm or accidentally ripping out their IV. I think it was their fortitude that frightened us. Sick people reminded us not of what we had, but of what we lacked. Everything we said sounded petty and insignificant; our complaints paled in the face of theirs, and without our complaints, there was nothing to say.
