Nobody cares if people are breaking the rules because most people on this thread are breaking the rules and carrying on with their plans.
They are the selfish ones op,
They are the reason we continue to be in this mess, you try and do the right thing by following the rules and you just get shouted at on here.
Mumsnet truly is awful.
Probably most people are following the rules, they just don't feel the need to shout about it.
Secondly in this situation, the OP does not know why the daughter is there, it may be a perfectly legitimate reason (as in allowed for in the guidelines) it might not, but if it is the former then don't add to their situation, and the latter is not going to be solved by standing at the window.
Hoardes of people or a rave in the garage the OP may have a fair point, but not for one daughter without knowing the ins and outs.
Obviously, unless the OP has changed details because "it is too outing" and it is actually her parents and sister. Not that that makes it better.
"As far as I know". Not enough evidence to accuse.
Absolutely. I'm not saying that this is what is at play here, but he may well be abusing her, the reason many victims of DV aren't believed is because all looks rosy from the outside.
My response would be "Goodness, I hope she is ok." Not "Evil rule breaker."
