I always have to have a shower at night. I just can't sleep if I go to bed with the days dirt on me. Plus there is nothing like slipping in between cool sheets when you are still hot from the shower. Then a quick shower in the morning to wake you up.
I do like a nice hot bath, especially on a winter night, when you've been outside and get cold. I take a good book and just relax. Now that we have a hot tub though, I go in there everynight!
