Barefoot on the subway is wild!
I don't think I could do that. I don't want to know what's on the floor of a subway, and definitely don't want to touch it with my bare skin.
Nah, you know EXACTLY what's on those floors and those seats: Hell. Hell is on the subway floor. The kind of Hell that takes 8 showers in one day to really wash off. The kind of Hell that creeps into broken skin and decimates an immune system in 5 minutes or less. The kind of Hell that makes everyone that eats off the floor and says, "God made dirt, and dirt don't hurt" look like the fucking morons they've already proven themselves to be.
Basically: You're smart.
