I don't know if it's because I never liked sleepovers when I was a child, but this quote from Battle Hymn of the Tiger Mother made sense to me.
Hard to argue with that!I wasn't going to let peer pressure get to me. The few times I did, I regretted it.
Once, for example, I allowed Sophie to attend a sleepover party. This was an exception. When I was little, my mother used to say, "Why do you need to sleep at someone else's house? What's wrong with your own family?" As a parent, I took the same position, but on this occasion Sophia begged me, and in a moment of uncharacteristic weakness, I finally gave in. The next morning, she came back not only exhausted (and unable to practice piano well) but crabby and miserable. It turns out sleepovers aren't fun at all for kids -- they can be a kind of punishment parents unknowingly inflict on their children through permissiveness. After pumping Sophia for information, I learned at A, B, and C had excluded D; B had gossiped viciously about E when she was in the other room; and F at age twelve had talked all night about her sexual exploits. Sophia didn't need to be exposed to the worst of Western society, and I wasn't going to let platitudes like "Children need to explore" or "They need to make their own mistakes" lead me astray.
