It's something that everyone knows, instinctively. It is a children's song. People know it all over the country. They don't know that I wrote it, which is the first test of a folk song. If you know who wrote it and associate it with that person, it usually isn't a folk song.
People write verses to that song all the time.
Many people have adopted it. I made it up out of things my children said to one another. People don't sing most of my songs. A lot of women like that song and identify with it. They identify with it on their own terms and have no idea why I wrote it.
