I've read a lot of threads recently where people are asking AIBU for things that just require a simple No!
Recent ones include a neighbour telling the OP she was having some parties and that the OP can't use her own garden - OP seemed to go along with this!
Another one about a 'friend' who stays at OP's house and doesn't lift a finger, pay towards anything and expects childcare!
There are many more, but AIBU to think people have become too afraid of upsetting people that they just go along with batshit crazy/ rude behaviour and requests? Not all confrontation is bad!
