I used to wear my underwear several days in a row, but now I change it every day. In fact, I change everything except that, on weekends, I'll sometimes wear the same pair of pants two days in a row. I used to dread doing laundry, but I pretty much enjoy it now. I don't iron, tho--I take my shirts straight out of the dryer and hang them up. If I sound like too much of a neat freak, well ... you should see my apartment. We can euphemistically call it bachelor style. I am getting better about washing the dishes. I do that every day instead of letting them pile up in the sink.
By the way, am I missing something with the famous Mary scene? Everyone else in the theater, including my date (a guy) was laughing hysterically. I am doubled over in vicarious pain. Just thinking about it makes me cringe.
Anyway, I don't know if I keep up with all the "guy things" (definitely not into sports, except to admire the athletes ...), but I'm a guy.
