Repairman: “Oh my god, it’s so hot in this classroom!

Us: “Yes sir it is! The heat goes too high and we can’t control it. Please help!”

Repairman (taking apart thermostat): “Oh, well here’s the problem! See these two tubes here? They are supposed to connect.”

Us: “Meaning…”

Repairman: “This is what regulates the heat. Without it, it just keeps blasting. Never goes lower or turns off. That’s why it’s so hot and stuffy in here.”

Us: “Great, well…that only took 3 years to figure out! Can you fix it?!”

Repairman: “Sure can. I’ll be right back!”

That was six weeks ago.

We never saw him again.
