DEAR MISS MANNERS: I live near a university, and graduate students are always looking for odd jobs to make extra money. One of them does my laundry twice a week, and always returns it beautifully folded. This week there was a surprise: a clean pair of red underwear with a reinforced, O-shaped opening in the crotch. It was quite well-made, and could represent a bit of an investment on a student budget. I’m no prude, and celebrate whatever sexuality may be expressed by this particular garment.
