Bus Trip

He was the only passenger on the double decker bus and he sat upstairs about halfway down the vehicle.
The heating was on full.
"Can you turn it off?" he shouted down to the driver.
"It's broken, just open the windows," came the return shout.
He did that and it became bearable.
Another passenger got on the bus at the next stop and came upstairs. They made the universal sign for it being too cold, hugging themselves and mimicking chattering teeth.
They went and closed all the windows, sealing in the heat and the rising smell of dried piss.
