Before becoming a parent I wondered about it too. Now I understand. Little kids are a disaster to one's brainpower and sanity. WFH with an infant next door is much harder. Going to an office to work really feels like a break instead of a chore.

In my life experience, myself included, I often knew about something a lot when, in fact, I really didn't. I suspect those that are down-voting us older people haven't yet experienced what we did or are.

I believe so. Before my daughter was born, I thought I knew what to expect. I was very wrong, but not in the things I thought I might be. A lot of minutiae of parenthood caught me by surprise - and ended up explaining mysteries like suddenly starting to enjoy the office.
