Setting: 5 year old son and his Opa working on fixing the kitchen cupboards.
Son: Hey Opa, do you have one of those stud finders?
Opa: No, but I know your Dad does.
Me: Yes, and you like to play with it don't you, Honey.
Son: Mom, I don't *play* with it. I *use* it.
Me: (mental note: right, boys play with toys...men use them. Got it!)
