YMMV. Plenty of groups out there to meet other parents and become friends with. I know several people who had kids and were SAHP and made lots of friends this way. Mind you, as the kids got older everyone moves around so friendships might not always last but it’s very possible. And you have a very obvious thing to bond over - being a parent.

I work at faang and have no friends from that. I’m surrounded by thousands of people every day I’m at work. Everyone is there to work - not be social or hangout or be friends. People show up to social events to grab food and take it back to their desk.
