I don’t get that at all. I assume it’s partly some ADHD or autism or what do i know. I had a girlfriend who would unbuckle her seatbelt 5min before we arrived and the car would just beep louder and louder and whatever. It drove me insane. I know it’s just a minor thing, but i never understood how you couldn’t be bothered with that. Especially because it’s very easy to not do that. I never got used to it, when she did it when i was driving, i would just stop and wait until she buckled up again.
