Actually we've rolled with it for years - up until now we've made this journey 6+ times a year. But this year I've noticed things are different - DD is in primary 1 now, she's tired and really needs her rest. If we leave the party at 6, it means home at 9.30, and DD won't be down until 10. It's just been a lot for her the last few times we did this, and sleeping on the bus isn't an option either, especially with all the changes.
And we host just as often as DB does. I've even had my nephews and niece to stay this year for a weekend while DB and DSIL went away together, and niece was only 10 months old at the time, so you can imagine it was hard work (I'm only used to one!). I don't mind - as I said, DB and I have always been close, and they've definitely been there for us - but it's not like it's a one way street.
Some people have asked: I don't have a license. I started taking lessons after DD was born, but I wasn't a fast learner, and then covid happened, and at the moment we are struggling financially, so right now it is what it is. But yes, I could (and probably should have) gotten my license when I was younger. It just wasn't a priority for me then. And it's generally fine: we live in a village and have everything within walking distance (school, supermarket, GP, sports etc) and I take the bus or bike to work (in the nearby city).
But yeah, DB and SIL's place is quite remote, they love their cars, and sometimes, despite the fact we get along great, our different lifestyles and choices cause tension. I think DB is / was very okay with my lack of car and lack of ambition (I have a job I like, but it isn't particularly well paid) as long as he could see us as kind of bohemian, just a bit alternative... but when it comes with actual limitations, it's a different story.
