I don't follow your logic, kiddo. Doesn't everybody in your household have their own towel? Or... do you expect that everybody uses a towel only once, then places it in the hamper soaking wet, and then puts a new towel on the rack? Me, I use towels for a few days before they go in the laundry, unless they're really dirty. (It would be really expensive and take up a ton of space to have a set of towels for every day of the week.) Between uses, they sit on the rack to dry. When I was a kid, each had our own bath towel, and would do the same thing. If you leave wet towels in the hamper for a few days, they're going to get moldy and gross - that's why you let them dry out, first. You're not going to die from using the same towel as a blood relative.

Shouldn't you be clean after you shower??? Its like using a dish towel to dry your dishes after you clean them.
