I don't think we WBU but I'm interested to see if there is another opinion because this has been bothering me since Saturday!
We live now in NYC. On Saturday afternoon, we went went with friends to Central Park. We were 4 adults, and 6 children between 9 and 3. The adults were sitting on some benches and the children were playing very close by. They were being noisy but not screaming or shouting at the top of their voices - just laughing and playing. We're not really listening to exactly what the kids are saying as we're chatting ourselves but they were happy sounds.
As we were preparing to leave, this man walks up to me and asks if the kids are mine. I say some. Then he says to me 'Well, you should know that your kids have been very rude'. I was surprised and asked him what they'd said, to which he cryptically answered 'You need to ask them'. I should have been more assertive at this point and insisted he tell me but turned to the kids and asked them what they'd said, they insisted nothing.
So I tell the other adults, who also ask the kids - no, they hadn't said anything. The other mum (a tougher than me New Yorker) went up to the guy as she really wanted to get to the bottom of it.
It turns out that the kids hadn't said anything TO or ABOUT this guy. What had actually happened was that on the lawn behind where we'd been sitting, there had been a couple who basically really needed to have found a room somewhere. They'd been full on snogging, she'd been straddling him etc. The kids had been laughing at this. This guy was very bothered that they were disturbing (apparently according to him - as far as I could see this couple weren't interested in anyone else apart from themselves) this couple who clearly were entitled to fondle one another in a public place in peace.
At this point he says to us 'I'm not saying you're bad parents' 'but your kids are just loud and annoying.'
If this had been a restaurant, a library, a theatre, then sure, fine. Loud kids are annoying. But a park on a Saturday afternoon? Given that in NYC most people live in apartments and don't have backyards - isn't a park one of the places where they are allowed to be loud (I'm guessing the annoying bit is a judgement call!)?? He was being totally unreasonable, right???
