"So would that include your workplace? What about the cinema for an adult film? If you go to a theme park do you expect your ticket to cover your kids too?"
I don't see it specified anywhere on my work contract that I am not to bring my children, nor do I see it on tickets. I'm quite confident that I can judge child friendly situations, and I do have enough common sense to make the decision confidently, on my own, without having it spelled out.
"So you're basically saying that your decision trumps whatever anyone else's wishes are. And how the fuck are you going to know whether or not children are not invited/welcome to a wedding if it's not specified on the invitation? Do you ring up everyone who invites you to check whether or not you can decide to take the children, or do you just assume "it's a wedding therefore I can take them"."
It's clear by the venue/times/overall formality of the wedding whether it's suitable for children. A quick google of the venue is usually enough to go by. Unless it is clear that it's very child friendly, I probably wouldn't take them anyway... and if it is unclear, I would ask. It's likely that if I have been invited to attend a wedding I'm on talking terms with the invitee and so it probably wouldn't warrant a special phone call.
But then maybe my view of this is skewed, because we had a very child friendly wedding and it was fantastic, the venue was such that it allowed the kids to wander around, we had entertainment in a seperate room, ate a reasonable time, everyone had a great time, both childless and 'with child' couples equally so. I don't recall any of the situations you mention coldtits. It's just a shame weddings have become so regimented. Just calm down a bit, it's one day.
