Visitor: “Excuse me, miss, is that a door?” *points to the door as two people walk through it*

Me: “Yes?”

Visitor: “Oh…well, can I walk through it?”

Me: “Yup, you sure can.”

Visitor: “Are you sure? I don’t remember there being a door here before.”

Me: “Ma’am, I can assure you that you are staring at a real door and it is perfectly safe to use.”

Visitor: “I’m confused. I’m just going to use the doors downstairs.”
