Preplanning? Forgetfulness?

Which is it?

Did somebody think about coming back to lock the bike/kayak/dog leash to this very spot at some point? Did they measure out the length of fencing and decide this was the spot?

Or, where they lost in thought about the book they'd just purchased from Village Books and snap the lock shut on their way home? Like me when I put the milk on the shelf and the cereal box in the fridge after my midnight snack?
