Teenage boys are not as good at babysitting as girls, by far. We've tried both. More often than not, the boys get carried away playing with our son (not all their fault, our son can get almost any kid amped-up playing) and they end up breaking something.
Tell me about it, I have 3 boys, had one of my best friends HS aged son offer to watch the boys, of course my guys were thrilled. Played football outside till they couldn't see the ball anymore, then moved inside, took mattresses off the bed and made one big wrestling mat in my family room. Needless to say my kids had a blast! LOL BTW, that young man, who I adore like my own child, is graduating from Parris Island tomorrow, he will be a Marine, I am so proud of him!!!!!
