I am organising an event and had space to invite 4 other couples- I decided to invite 2 friends first and both accepted- that left 2 places left- I have a chat group with three other friends so messaged to say I had 2 places left. 2 friends accepted and the the third friend messaged to say that I had been very unfair to invite 3 people if only 2 could go and that I'd really upset her and she was leaving the chat group. I messaged to say we could organise extra places but she was having none of it. Was it terrible of me to invite 3 couples for 2 places?
