I disagree with that. I am sure it happens to a few kids a year, but for the most part that isn’t it.
In my paternal family, mine was the first generation in three centuries that did not attend boarding school.
If I could ask you a question on that, how is that changing the family dynamics?
Its one thing if your kids were away at boarding school for most of the year, another when they are always home and you have to deal with them more. Is that causing some issues with parents and grandparents adjusting to the changes? Is it hard to get used to PTA, helping kids with homework, Being the person who must pick the kid up everyday and take them to daily events, being there for more events, and having your kids school seen in context with your immediate community?
Example: My wife was a nanny for this woman who was raised in a boarding school and she honestly said she had no idea how a “normal” teenager’s life is like or what going to a regular school is like because she never was a part of it. Growing up her parents interaction with the school was only thru grade cards and the rare visit.
