my car keys were on the roof of the car and other (paint shop window) shards

One of those days, one of those weeks.

Unplanned and contracted construction job incoming: noticed a crack across the big window (6'x5') in the paint shop and have someone coming to fix not only that but to replace the side door and two of the basement windows. Decided it was time to get the latter items off my plate by having someone more than YouTube-competent do them.

Titular keys on the roof were directly related to the cracked window: as I had neglected to take the cardboard to recycling for a week, I had a ton of cardboard in my trunk which I recycled into a makeshift window covering held on with all-weather duct tape and, in the excitement, left the car keys on the roof all afternoon and evening noticing them only when I went to bed and saw, from the landing, a weird splotch on the top of the car which was determined, upon inspection, to indeed be said keys. They were cold. May have borked a fob. Oops.

Happy thing: I fixed the outdoor motion sensor light - pre-bedtime dogchild piss'n'shit will be illuminated once more: "Perhaps we may frighten away the ghost of so many years ago with a little illumination (cue Phantom overture)..."
