Thanks for linking to that. I was JUST talking to a young colleague of mine today about this: she and her fiance are moving to NYC, plan to stay a couple of years. I told her emphatically that they MUST be persistent about doing all the things they’ll only be able to do easily while they’re kid-free, because one of these days, regardless of how much money they happen to make, PARENTAL LOGISTICS will become Operational Topic #1 in their lives.
