Just wondered really. DS has often brought up leaving home, asked about ages that people move out, and has occasionally asked whether he can live with another family. It's happening a lot more now he's at home so much for the holidays, although we spend much of the time round at friends' houses, activities and so on. He does hate being an only child and I do know that, but it's not going to change. It does seem to me that the sheer amount he asks about it is unusual, but maybe lots of kids of his sort of age ask this?
