I'm interested in people's opinions of this.
I was putting baby dd in the car in her car seat. I have a tiny car which means I had to use the road side to put her in (isofix seat fitted in other side). I leaned in to strap her in and stepped inside the car for a moment to put the buckle in. The road is very quiet.
Another car then comes round and closes the cars door. Aibu to think this is a bit rude? If he had asked I would have closed the door. I didn't realise it was causing an obstruction.
