Conversation with my 10 y.o. son today @ 7:a:
Son: Hey Dad, what are those?
Me: They’re lug nuts. I gotta return them.
Son: How come?
Me: (trying to dumb it down) Well Son, I have a different thread pitch and need the right size. You know when a bolt and nut go together? The little lines are called threads and I need the right size to make them fit and hold properly.
Son: You mean to keep your wheel on your axles?
Me: Go to school Son
