Outdoors is another situation entirely and also interesting. My cousins all lived in rural areas and grew up going barefoot. I lived in the city and never went barefoot. Even at night at home I'd wear socks around, but didn't go barefoot outdoors. Now when my cousin stepped on some glass that even further lessened by barefoot desires and then when we were boating and a friends cousin stepped on glass when we were in the water close to a dam I stopped going barefoot walking in the lake. I do go barefoot at home in our back yard, on the patio, and by the pool. However, I know there's no glass or cans or anything else there.
I'm a wimp. I admit it. The thought of stepping on glass or a rusty can does scare me.
