Midnight is hardly "an early night" 😂 And it's different if they are up for a house related task, but this is people being selfish. I don't like Kerry, but with her health issues she may need more sleep than others, for example. You can argue "well don't go in the BB house if you can't hack it" but I'd argue it's about common human decency.
Each to their own. I actually find it fascinating finding out from here (and watching BB) how people can have such different opinions on what is basic respect. And what behaviours should be expected of grown adults. In my opinion much of it comes down to the fact that some people are much more entitled, and others are more thoughtful and considerate 🤷🏼♀️
