Ok, first off, I know this isn't up there with the worst things that could happen, but...
Today DH and I are both working from home. On Tuesdays DC are collected from school/looked after by DM - as has been the case for about 3 years. They finish school at 2:55 and 3:05. At 3:15 DH asks me if I'm ok to pick up the kids today.
Admittedly youngest DC has just started school and I've recently slightly changed my working pattern, so there are some new routines to get used to, but still AIBU to find this apparent lack of awareness quite annoying?
