But namechange although you are quite rightly horrified by the thought of deliberately malicious gossip I don't think that's what Rhi intended to describe, nor what would happen in real life.
I was seriously pissed off about the whole situation with X & Y.
Y's behaviour really spoilt my DD's party for her.
Would I have been unreasonable if I'd vented about it to a friend? I don't think so.
I can well imagine that if that friend was later in a situation where twin invites were being discussed she might say:
"Scarlett always encourages people to invite Miss Freestone and Master Freestone separately but she was really annoyed that X's mother manouvered her into inviting Y to their last party, particularly as he was a little horror"
Suddenly 5 or 6 people at that coffee/lunch/night out know that not only does Mrs X&Y insist on both her twins being invited but that Y is a mean bully.
You are being naive if you think that's not how social life operates.
I know couples whose kid's bad behaviour has caused them to be dropped off dinner party invitations.
I know women who no longer get invited to parties because their husbands are irritating, drunken arses.
People discuss other people's bad behaviour (it's what we're all doing right now). If you insist both twins have to be invited to every party and play date word will get round and invitations will drop off.
Twins are not two halves of one person. They shouldn't be treated as a unit.
It might be cute or convenient to view things that way while they are little but it's damaging to them.
They aren't going to go through life as "the twins" always having identical matching social lives so it's a poor decision to allow them to think they should.
If twin one gets more invitations because they are more socially adept them shoehorning twin two into every event isn't going to help that child develop either the social skills or coping mechanisms required for later life.
