Spose its a bit like the carp fishing game.... If everyone worried more about what their up to, and not what everyone else is up to, then everyone would be better off.
As I said, I`m pretty sure its just an occasional day out for all the kids. How is a child supposed to enjoy the day when their getting told to be quiet, stand still, and dont do that every 2 minutes. I never said it was my cup of tea, but I certainly wouldnt knock a fella for getting out with his mates and family.
