What do you wash your towels with?
Soap and water.
What gets on your towels when you use them?
Soap and water.
And towels don't get dirty, how could they? You don't use them unless you're already clean. So then why do you have to wash towels? Aren't they getting washed each time you use them?
Maybe the problem is that, eventually, all that soap residue builds up, so when you use the towel you just get all lathered up again. But then that means that, when you wash towels, you're using soap to clean off soap.
Don't think about that idea for too long, it's like an Escher painting for your mind.*
Washing dishes is strange too. Ever had a sink full of dishes that you've been meaning to wash for three or four days? I do right now. But clearly I'm getting along just fine without those dishes, so do I even need them? What the heck have I been drinking out of these past four days? I can't remember.
I guess I don't need towels either, for that matter. I mean I'm going to be dry eventually. Towels are just there for my impatience. I refuse to drip dry for ten minutes, I'd rather towel dry for three minutes and then do a whole extra load of laundry every week.
And speaking of cleaning, how come so many "earthy" people who "love nature" also keep really clean houses. It seems like they'd never have to clean, dirt and bacteria are some of the most natural things in the world. "Why do you have a vacuum, don't you love all this nature on your floor? Take my shoes off? Why? I'm just tracking in nature! Oooh, look what nature is growing with the little bit of milk left in this glass!"
People forget that most of Nature is trying to kill you.
