Person A is celebrating a big birthday next year and as they've been meaning to go on a holiday together, has planned to go on a holiday with B, C, and D.
A's boyfriend also wants to go to this destination and is willing to pay for A. A thinks its a waste of time and money going to the same destination twice and would like her boyfriend to join the group trip.
B and C are against this as they don't know A's boyfriend (having only met him once) and think he'll change the dynamic of the group and they won't be able to let their hair down. A argues that her boyfriend is laid back and won't change the group dynamic.
D doesn't mind if the boyfriend comes.
