Maybe I'm overreacting but this is bothering me.
A few days ago, DH was on his way back from taking the car to the garage and saw a very little boy aged about 2 standing alone at the side of a busy main road. He was so alarmed he went round the roundabout and came back up to look again and the child was there, definitely alone. Hubby pulled over and was just deciding what to do (he's a big, rather intimidating-looking guy, although a very kind/gentle person). He then saw a couple of other people approach the child so he joined them. The kid wouldn't say anything but pointed vaguely across the road, and one of the other people crossed over and walked up the road and said there was an open door up there, so the group of them walked the child across the road and up to the house. They knocked, and a lady came out, so they asked her if this was her child. She said 'yes' and they then told her they'd found him at the other side of the very busy road, further down the road. She just kind of rolled her eyes and said something lame like 'Oh dear' and then shut the door.
I think this is a REALLY bizarre way to react to a group of strangers arriving at the door with your child and finding out that your very tiny tot has crossed the road unaccompanied and wandered off. I know not everyone reacts the same and can possibly understand why she hadn't realised he'd wandered off (MAYBE) but the story made me uneasy and I felt DH should phone SS to follow up, but he says that's an overreaction.
