Is it wrong for a man to use a bronzing moisturizing lotion? Is it wrong to even ask that question outside of the privacy of one's own home? I think the answers are "no" and "yes", in that order.
Have you ever walked down the street (or been on a train, bus, etc.) and thought, "I wonder if that guy is crazy, truly mentally insane. I mean, look at him, he must be. There is at least a 75% chance that guy is crazy," or something to that effect? I do all the time. Or at least I did all the time when I rode the metro daily. Point being, how many times do you think someone has looked at you and thought the same thing (or maybe, "I wonder if that guy is homeless?")? I'm sure people have thought I was crazy, although I don't know about homeless.
At what point in a relationship is it appropriate to tell someone that they have something in their teeth, on their face, etc.? The day you meet someone? Do you have to be good friends? Carnal knowledge?
Why does the river outside of my window look like it is flowing North when I know for a fact that it is flowing South (I don't think anyone can answer this without actually coming to my office and looking, but I'm perplexed nonetheless)?
I absolutely despise the phrase "to wit".
