How low can you go?

It's the Wacky Tiffy Dog and Pony Show again!

Tiff has adjusted her desk chair to an unreasonably low depth and it's hard for me to function in it if I happen to be at her desk. Yesterday, I needed to use a program on her computer and rolled my own chair across the room so that I could sit more normally. When she came in and sat in (her) chair at my desk, she said, "Man, your chair is REALLY low!!"

I blinked at her a few times and said, "Um, that's *your* chair."

"Oh. It is?"

I just smiled. To respond just prolongs the agony.
