It was raining on a jobsite one time, so, having finished my estimations, I tucked my brand new (days old) laptop on top of my front-left 42" Super-Swamper so it would not get wet as I talked with the contractor.
As we finished our conversation, I hopped up into the cab and drove away, completely forgetting about the laptop resting on top of the tire, inside the fender well.
An expensive lapse in attention, to be sure. : (
Ouch!
I did that with a pizza one time. Picked it up at Giuseppe’s Pizza, put it on the roof of my car to get my keys out, jumped in the car and drove away. That pizza ended up in the middle of the first intersection I came to.
