This irritated me at the time and is playing on my mind now...
I took ds (5) to the park earlier with his younger brother. When we got to the play area it was empty apart from a girl around the same age as ds whose parents (presumably) were sitting on benches outside the play area, able to see her but not to hear anything unless it was shouting.
As soon as the dc and I entered the girl made a beeline for us, not surprisingly. She did the usual 5 year old thing of talking 'at' me, which was obviously fine. She was telling me about her school, her teacher etc etc. The problem was, ds kept trying to engage with her and was responding with details about his school and so on. Ds is a talker anyway and needs persuading to stop chewing my ear off and go on the slide! However, the girl was totally blanking ds and kept directing all her comments to me. I was replying but also trying to involve ds? 'That sounds good, ds likes that book too ....' only because he wanted to join in. The girl was resolutely ignoring him.
It went on like that for a little while and then suddenly ds just started howling and buried his face in my skirt, like a child in a story. He's not a big crier at all and has never done the burying his face thing before. I was completely taken aback. Of course we left, and as we crossed the playground, I saw the girl's adults staring at us and shaking their heads and as we passed them one of them said, 'oh dear.' I was pretty pissed off at that point. Their child was bored and lonely and needed some adult interaction and they were just sat there and then said 'oh dear' about my child! So I said, not particularly loudly, 'you might want to try interacting with your child...' No idea if they heard me though.
AIBU to think that their parenting was pretty shit?
