Groceries

I don't always carry all the groceries on one arm, but when I do, my keys are in the wrong pocket.

My kid has an uncanny knack for deciding to take out the trash while I'm grocery shopping and locking the dead bolt behind him when he goes back in.

At least they're in your pocket. Nothing compares to the feeling of checking both pockets, then noticing something shiny dangling from the ignition and that all the doors are locked. Naturally, it then begins raining.

Don't ask how I know.
