Don't do simple maintenance when you're preoccupied

I wanted to fill my windshield washer resevior, after dumping in a half gallon I realized I had filled my radiator resevior. Had to siphon it all out and make a last minute run to the auto parts store.
Damn manufacturers shouldn't make both fill caps yellow

Yikes! Good reminder
