I'm sorry you find DH and me such inadequate humans 😂We meet many of your criteria. I don't think we're weirdos; have a glimpse into our world and see what you make to it ☺️
Kids parties are really dull on your own, especially when conversation runs dry with the other parents. Those parties in Reception were loooong. And very, very regular.
We do pick up on the way home from work. It would feel really odd for one of us to sit in the car and gaze out of the window/at the phone whilst the other went to pick her up (in Y3/4 we still have to go over to where their classrooms are to get them rather than wait in the car park for them to come to us).
During term time, we generally go to the supermarket before we go and pick her up from a sports match on Saturday mornings. We both want to see her play a bit (but not necessarily the whole match, see above re other parents and parties). During the holidays I suppose it's just habit to go together and DD enjoys ticking things off the list. To be honest I'd never really thought about it.
We went together to the Reception info evening because we were both really excited about her starting school - it seemed a huge step and we wanted to soak it all in. We're over that one now 😂.
I don't think we would ever say we refuse other plans, but we do prioritise family time. During the week we only see her for a couple of hours max in the evenings as she has to be in school by 0810 and goes to after school club so we can work. We don't usually pick her up until 1745, she's in bed at 1930 and has to have dinner and do music practice in that time.
I wouldn't have commented that you were amazing for taking your kids out and I wouldn't show up at DH's function (unless it was joint friends or something).
We're only ever invited to family things as a family, so that means all three of us. That might be influenced by the fact that neither DH nor I have much in the way of extended family, so it's mostly the GPs plus us.
I guess we might look very insular to you as you'd see us together a lot. It's not that we can't do anything apart it's governed more by convenience and our particular circumstances.
I don't hate the other school parents by the way, they are nice people and I am quite friendly with some of them. We don't have a huge amount in common with them besides school though, and there's only so many times I can discuss whether Miss Jones is more strict than Mr Brown!!
