“It was the same last year when two new girls were introduced (Ellie and Zara??) and all the guys were invited downstairs to have drinks and chat with them first while the girls were left on the balcony to watch over them for ages before being allowed to come down.”
They have done exactly the same to the boys over the years with them watching from the balcony. They will probably do it this year. The boys never behaved like that, and they won’t when faced with the same situation.
