Following on from another thread (is that allowed on mumsnet? I'm a fairly new poster) WIBU to get annoyed on holiday when my adult dd asked me to make the only loo in the caravan a non poo loo? She wanted everyone to go to the public loos instead. 
What got me was that I had paid for everyone to come on holiday together and was being told I couldn't use the loo when I wanted for what I wanted.
I refused to do as she asked and everyone, except her, used the caravan loo as they saw fit.
