School pickup time in a park and stride type of carpark and I'm waiting for ds. Small child (3/4 years ish) comes hurtling into carpark on scooter alongside a car which is just pulling out of space (it's a 4x4 and the child being approx 2 foot high the driver had no way of seeing he was alongside her as he was parallel with the car about a foot away the whole time) as she pulls out he gets to the front of the car and skirts around it still a foot away apparently oblivious to the fact the car is moving and as he is central to the bonnet he moves out slightly and driver sees him and stops. She looks horrified as am I and we both look around for an obvious parent - no one!. She drives away looking shaken. A couple of minutes later two women amble along with another smaller child and I ask if the boy on the scooter is with them - they are immediately shifty and say which child - I say the small one with the other children (who had arrived earlier) over there, they say yes looking cagey. I say he was almost just run over, came alongside a car and the driver had no chance of seeing him, she only just stopped in time. They say nothing, then in a snotty tone - thanks for letting us know. Ds said I shouldn't have said anything. WIU?
