"People seem to do this all the time without much thought:"

I do it all the time with that because I know otherwise leads to catastrophe.

I want set a tell a woman I was going to be late for a date because I couldn't find my car keys. For some unknown reason I'd put them in the grocery bag and put the grocery bag directly into the refrigerator. It took me hours to find--hours I hadn't planned on because I usually put my keys in the same spot to avoid the nearly certain trouble that happens when I assume my future self will just remember what I did.
