It seems like a fair trade to us. They stop muttering one stupid comment after another, and you'll stop responding with a barbed rejoinder. You wouldn't need to use sarcasm so often if people would just stop it with the inane drivel they keep subjecting you to. It's not as if you enjoy being such a smartass. Well, okay, you do enjoy it. But some people deserve killing and many, many others deserve sarcasm. You're just performing a public service here. Wear this tee and stay on the mission.
