I don't get the composting toilet thing, either. They're all the rage in "Tiny Houses", which is another fad that I just don't understand. My fiance won't let me watch any of the Tiny House shows anymore because all I do is complain for the entire episode. "I want a tiny house, but it has to be 400 square feet, have a room for the kids, an art studio, gourmet kitchen, full bathtub and a porch....and a regular toilet" And then they talk about the "freedom" these bloated monstrosities give them. Really? You're going to hook it up to your Prius?
Ahhh I feel better now.
