Actually, I take back the "no laundry sitting" thing - there's a basket of towels on a coffee table that never got folded... which, in my mind, isn't quite the same thing as letting shirts, etc. sit. And socks and underwear? Yeah... those get tossed in to a smaller, separate basket to be dealt with at a different time (usually after all the "real clothes" are folded) XD
The temperature and humidity is probably factoring in to your hair not getting dried. I remember that happening to me sometimes too when I was living in the north.
