Then again, the worst offender was also the most condescending person I've ever met, and I put him in his place. He was dead sure that all of his students were fresh out of high school with no real life experience, and said as much constantly. He showed us a painting called "Absinthe Drinkers" (google it, I'm lazy) and told us that it was not legal in the States and then asked in the most prickish way possible if any of us had ever had it, so I raised my hand. When he asked (still being a prick) where I could have possibly had absinthe, I told him, "Well, I drank it with my ex-husband when I was stationed in Germany 3 years ago."
