Yes, I'm another CD who's done "quasi-purges" by packing everything up. My usual trick is to put the boxes in a storage locker, so I can get them back, but not on the spur of the moment.
As for what how to respond to people who ask why you're hairless, I'm tempted to say that anyone who'd ask is, by definition, a rude ass, and you don't owe them anything more than a withering look coupled with "It's none of your business." Or if you really want to stick it to your questioner, say that it's from your chemotherapy.
Of course, that last line can get you in BIG trouble, so use it with care!
If you want a less obnoxious response, point out that most TV and movie actors are hairless. The next time you see a guy take off his shirt on TV, check out his chest hair. Odds are, he has none. Ditto with rock stars.
Personally, though, I don't normally shave my body. I'm hairy. I mean, really hairy. Ten years ago, for medical reasons, I had to shave from the neck down. That had its advantages -- I dried off a lot faster after a shower! -- and every time I got undressed, I was astonished by how different I looked. But ultimately, I stopped shaving. It was just too hard to do it, and the stubble itched like crazy!
These days, I go for the covered-up look: opaque tights, long sleeves, and high necks. Or if I want to wear something with straps, I wear a thin long-sleeved turtleneck leotard under it.
