A friend group is on the brink of collapse post-holiday – and one of them is blaming it on their friend being an only child. 

She told So You Think You’re an Adult she and three friends had been planning the holiday “for months”. 

“The majority of us are fairly laid back so we kept our plans and bookings loose to decide on things together,” she told Moncrieff. 

“However, one of my friends took completely over and essentially forced us into whatever activity she wanted to do.” 

She agreed it’s always good to have an organised friend on a holiday – but her friend would “literally throw tantrums” if the group didn’t do what she wanted. 

She said her friend rarely acts like this - but it’s the perfect example of “only child syndrome”. 

“She never acts like this one-on-one – it's only whenever we're in a group,” she said. 

The woman and her two other friends have now made a separate group chat – and have agreed never to go on holiday with their only child friend again. 

Broadcaster Declan Buckley said the best time to call out their friend’s behaviour would have been on the holiday itself. 

“Call out the crazy childlike behaviour when it's happening and you also say what it is that should be happening,” he said. 

“Unless you have an alternative suggestion at the moment, you’re actually complicit. 

“[Not saying] you don’t like an idea because of X, Y and Z and then passive-aggressively making a group chat after – that's not very mature behaviour.” 

He said he was “calling bullshit” on the suggestion the friend was rude because she is an only child. 

Only child syndrome?

Actress and proud only child Mary McEvoy said only children typically avoid conflict since they didn’t argue with siblings growing up. 

She said if the behaviour of their friend is surprising, they should find out more before alienating her. 

“Check up on her and see if she’s okay,” she suggested. “If she’s okay, she’s a weapon.” 

Declan also pointed out some friends just aren’t suited to go on holidays together – especially when they have different ideas of a good break.
