This isn't child related, but it's a good anecdote.
My cousin (let's call her Barbie) and her husband (let's call him Ken)...
Ken had bought Barbie a particular spec of a very snazzy car. So particular, in fact, that they waited about 6 months for the dealer to track one down.
Plenty of moolah involved...
Now Barbie was no flake, she was always sensible and had her head screwed on. So she had a minor lapse of concentration...
I talk about her in the past tense, as she died a few years ago.
First day with the car, off she pops to do some shopping and she parks the car and goes to Sainsbury's.
20 minutes later, she realises she can't find her car keys and realises that she left them in the ignition of the car.
She hustles back to the car, which has (of course) been stolen.
She scuttles home in a cab and has to confess to Ken what happened.
They didn't argue, he just walked away, cos he didn't even want to look at her.
Needless to say he wasn't happy and didn't talk to her for a few days.
Barbie was a bit 😬 and felt dreadful, bless her.
Then her mum (let's call her Sindy) had to sit Ken down and tell him that he has to get past it.
It was only a car, at the end of the day and nobody was hurt, etc.
Otherwise the incident would have continued to be a black cloud in their relationship.
Under the circumstances, it was the right thing to do, I think; and their relationship did bounce back, thankfully.
