When the delivery driver knocks at the door with the LARGE pizza I ordered, I call out "Pizza's here".
I live by myself, but hopefully he believes I'm sharing my food.
I have an extremely strong sense of smell. I am often referred to as a drug detection dog (Dutch wording, though). It's usually more frustrating than useful.
Whenever I take a shower, I'm always commenting out loud like "Oooooh, that feels nice," "Aaaaaah, so refreshing," "Eeeeeeh, that's exactly what I needed."
