I absolutely can’t stand when people neglect to dry their hands after washing them. No, not neglect, that doesn’t seem to be the right word. They refuse. It irritates me when done in public bathrooms, simply because it means that my hands get wet when I open the door, but it drives me insane when it’s done in my house. The flush handle, the doorknob, and everything they subsequently touch gets wet, and I inevitably end up touching it myself. Use a damn towel, will you?
