I'm genuinely not sure how cross I should be.
My dad has a convertible and my DS (2.7)loves cars. We were getting ready to go swimming when staying at my parents' a few days ago, and my dad took DS outside to sit in the car (which was on the drive),which he's done once or twice before. When I came out the car was in the garage and my dad told me he'd driven the car into the garage with DS in the passenger seat - no seatbelt, and obviously no child seat so even a seat belt not very helpful.
I was quite angry as I said even though it is a tiny tiny chance, what if my dad had a heart attack and car lurched forwards (or similar). It was literally a case of driving 10 metres or so on a sloping driveway, so I know the chance of danger was infinitesimal. However, I also believe in avoiding easily avoidable hazards. My dad clearly didn't think I would mind and wasn't secretive about it.
I told my dad he needed to promise me never to do that again. He didn't take me seriously and tried to make a fake jokey promise but I made him do a proper promise. Then I dropped the issue as we were all going out and I didn't want to have a big discussion.
I can't discuss with my DH as he would be furious and I don't want to put his relationship with his PIL under strain. But I know my dad and my mum think I was being OTT and as I've thought about it more I really don't know? Am I being PFB (I know I can be) or is it a generational thing but reasonable of me?
