Things That Have No Reason to Exist in Our Society But Inexplicably Still Do

OK, tell me if this sounds fun: I salivate all over something sticky, and then I put that sticky thing in a place where you are accidentally going to touch it when you least expect it, and because you have no idea how clean the inside of my mouth is, you have no idea if you are now going to get some hideous disease.

If you are a sensible person, that should sound horrible to you. But if you are one of those people who sticks their chewed gum in public places, then that is exactly what you do every single day. There are trash cans everywhere, people. Stop soiling everything with your used gum.
