The quiet game.
I have four kids, girls triplets age 5 and a three year old son. Sometimes they can get so annoying and loud. So when I need peace and quiet I tell them let's play the quiet games. Whoever is quiet for two hours get $5. And it's funny because when I tell them to be quiet without saying I'll give them money they are loud. But when I say quiet time they are perfect little angels. Is it normal they don't listen without my bribe of money?
