My boys are duct taping each other to chairs. For fun.
Apparently, this is what they do for fun when I'm otherwise occupied. I was on the computer, doing some online banking, when I heard, "Mom, come look!"
Son #1 was completely duct taped to his chair. Son #3 was grinning. Son #2 was watching the clock. It took Son #1 less than a minute to break his bonds.
Somehow, I just can't see a group of girls playing the same game.
