Replying To Maroonatic:  "Akin to getting an invite from your neighbours to come round for dinner some evening and join them in a few games of gin rummy. They think you're a bit exotic and would brighten up what's become a drab social event for them otherwise. So you say 'Sure, we'd enjoy that we'll bring the kids with us'. At which stage they shuffle their feet awkwardly and tell you, '...ummm...about that. We would rather ye didn't. Your kids are more advanced than ours and it wouldn't be good for our little darlings development. Oh and there's no need to invite us to yours in return as we're home birds really and we hear it rains a lot that side of the river'"
