She’s picked him up almost every Wednesday since the school year started. So...give or take 10 times?
Today she texted me and asked what the schools address is again, she couldn’t remember. (FWIW we’re in Manhattan where no one uses addresses, you just know what the cross streets are)

I think this is very very strange. My SIL (also her MIL) agrees. My husband does not. FWIW my MIL drives me crazy so I could be very biased. That’s why I’m asking here 😜
(To be clear, this isn’t a weird isolated incident. That’s why it’s concerning to me. If this was the only thing that’s happened in the 4 years I’ve had kids, I would maybe shrug it off or just keep it in mind).
