Messy eating (eating with my hands, wiping my mouth with the back of my hand).
Wiping wet hands on my clothes to avoid wasting a paper towel.
Not showering for 3 days.
Re-wearing shirts, pants, socks, running shorts, and sports bras multiple times before I wash them.
Eating food off the ground.
Not flushing the toilet when I pee to save water.
Bringing my backpack everywhere, which I set on the floor and bring into the wilderness. It has never been washed.
Sleeping with my mattress on the floor instead of in a bed frame.
Chewing on the ends of pens.
Sitting cross-legged. In skirts.
I'm writing my own as a comment on this post!
None of these things are disgusting! :)
