When I go around locking doors at night before bed, I stick my head out into the garage "to make sure the door's closed."
But it's really to say goodnight to the cars. They like it.
My 19-month-old son has taken to dragging a stuffed puppy dog around everyewhere he goes. I've seen him try to give the stuffed animal milk and pretzels. He also kisses it a lot. To a certain extent, I think sports cars are stuffed animals for grownups. Not that I kiss my cars...usually.
PS - I think we should be able to vote for "my wife thinks I'm crazy" AND "Once a day."
