To be fair, I would have been equally horrified by that at 13. Conversely, I came from a family who had travelled, emigrated, lived all around the world. When we moved to the UK and there were kids at school with parents who had also been to that school and had always lived in the same house etc, I found it baffling! I was adamant there was no way that would ever be me and I was very derisive of that sort of set up.
Anyway, I did travel and I have lived abroad and dh and I moved to a vibrant city away from our families, but guess what? We really miss them and are now planning to move closer to them.
I am a teacher now and I really value a sense of community. I work with people who went to the school and really enjoy seeing families work their way through - at the moment I've only seen siblings but if I stay long enough, it will be amazing to see children of previous students! However, I may well end up working at the school I attended when we moved here, with the move in the pipeline, and I'd be thrilled. I don't see it as horrifying or stifling or sad anymore.
Don't take it to heart. If your dd does as she says then great! If she doesn't, don't throw it back in her face. She's young and she sees the world as her oyster, as she absolutely should! One day she may reflect on her words, as I know I have, but equally it may have just been a throw-away comment and she'll have forgotten all about it.
