If she’s staying in California, it’s expensive. You can’t expect those kids to start going to a regular public school if they’ve been in private school. You can’t expect them to hangout with their friends, and the friends have nice things, and they have to bring $20 in a card for a birthday gift. If they have tennis lessons, or horseback riding lessons, you can’t expect them to stop, and play on the street courts.
We’re all looking at this from the perspective of people living regular lives, and the most luxury our kids get is a trip to Disney World once a year.
