A least favorite thing in my life is when my kids have been working, playing, studying, inventing, creating etc. all day and then they have a 5-min. lull. "I'm bored". I very strongly dislike that statement!
Mom's never have time to get bored. At least most of the ones that I know. Our list of things-to-do never has an end -- and we always have pending projects or chores.
My sister says that it's good that kids get bored -- because then they have to be creative and think of something to do.
I've often given them the list of possibilities; chores, books, crafts, service, sports etc. but that never seems to really help. Apparently they have to think of things on their own most of the time. So, I've learned to say 'oh, I'm sorry. I hope you'll find something to do'. And, then often add under my breath (for reinforcements' sake) 'Mothers never have time to be bored" (hopefully someday they'll catch the hint.)
