Think of something that you do, that you would think a lot of other people wouldn't do. Like "Am I the only one who pours milk then cereal then bowl?"

Am I the only one who turns on my air conditioner just for the noise?
Even if it's kinda cold outside but it's silent in my room, I might turn on my air conditioner to a low setting, just for the noise. Long silence makes me uncomfortable
