You also have no idea and are projecting your personal tastes onto others.You’re imagining his wife and kids would prefer LA? That’s just another way of saying you have no idea. Or maybe you’ve spoken to them and they told you. I don’t get the assumption by many that anyone with a family would prefer to live in LA. I can think if hundreds of places I’d rather live.
Conversely, LA area is also better than "hundreds of places"
