So the consensus is I’m being unreasonable - but what about the safety aspect? Some of the cars drive in quite fast and usually the kids notice and get out of the way but it does worry me that an accident could happen.
No, you are not being unreasonable.
Kids playing out in the street is one thing, a car park is not the right place for kicking a football around - as the HA rightly points out by asking that children don't play in it.
I know we are all supposed to be delighted that kids are out instead of glued to their screens indoors, but it's not unreasonable to expect them to behave with a little consideration for others, and to obey the HA rules.
There's two good reasons why a car-park is not a suitable football playground - the possibility of damage to the cars, and the more serious danger of one of the kids being hit by a car driving in or out.
Why the heck can't the parents spend some time taking them to the nearest playing field for a couple of hours? I will probably get criticised for saying this, but some parents clearly just can't be bothered.
I once found my son repetitively kicking a ball in our joint courtyard belonging to our block of flats - in fact it was the noise that alerted me, the continuous banging against the neighbouring fence. So, tedious as it was, I accompanied him with some mates to the park, which was a bit of a walk away, so they could play football properly, without annoying anyone.
It's a bore though, and I was a full-time working single parent and would much rather have been indoors catching up with housework and leisure time, but that's what you have to do with kids during holidays. Not just shove them out the door so you can get on with your own life. I also got together with other parents of my son's friends, and we took it in turns to not only take them to the park, but to McDonald's sometimes.
I've no patience with lazy parenting, which, I suspect it is in some cases.
