Old One Arm

Tomorrow my husband is having surgery on his left hand to relieve carpal tunnel pain. The hand will be mostly immobilized for two weeks, from the middle of the fingers to almost the elbow. Yesterday the husband chastised me, and practically suggested I was a blooming idiot, because I expressed concern at his statement that OF COURSE he would be able to drive his truck with only the right hand functioning. Okay so it's an automatic transmission, but still. Are my nitwit neurons in full bloom, or what? Sigh.
