When Tim got home from work today, Tillie managed to find his keys. She proceeded to walk around the house "locking" and "unlocking" things like the fridge and kitchen pantry.
A little bit later Tim was going to go on a walk with Tillie and mentioned he couldn't find his keys after Tillie took them. I told them to go and I would find them while there were gone. I did find them, but it took me longer than it should have.
