We solved that one quickly.....when those words were uttered by our children we'd say "Boredom equals choredom" and set them to work.
LOL. My mother and father used to say the same type of thing to us kids. "Well, there's a vaccum cleaner in there that needs some use." or "The car needs washing."
But now it has backfired on my mother. She is retired and every once in a while she tells me she is bored. I get a big grin on my face and tell her, "Well, I'm sure you have a vaccum cleaner that needs some use . . . "
