Generalization

I'm a bit "off of my rocker" today. Earlier, I spent 10 seconds waving my hand in front of a paper towel dispenser, waiting for it to pump out paper towels... it turned out to be a manual dispenser.

Then, a few hours later, I spent 10 minutes trying to use the ATM machine with no luck, only to realize that I had stuck my credit card into the ATM machine, and not my debit card.

Eek.
