It is natural that our habits that seem bad to others seem good to us. A woman who was a chainsmoker of cigarettes blew the smoke into the face of a man sitting with her on a sightseeing bus. He was a tobacco-chewer, and spat out the window. She blurted out, "Chewing tobacco is a filthy habit."
He replied mildly, "Well, ma'am, it ain't never started any forest fires."
