Like, for example, when I buy something, pull the sticker off, and it leaves a thick residue that won't come off. Or, when I'm in a car without any indication of which side the gas tank is on.
My significant other makes fun of me for this. "Who thought doing THIS was a good idea? Do they buy their own f*ing products?" I'll say. Meanwhile, he has a non-founder view of life, "Meh, it's like that because it's like that."
He's clearly more zen than I am.
