My sister is annoyed for not inviting her son (my nephew) to CP.
I have booked a lodge to celebrate my birthday, and there is room for 1 more person, however I don't want anyone else to come. The issue I have is that she treats my nephew like a child when he is an adult, therefore I am going to have to collect him and take him home, that adds an extra hour to the car journey (it already takes 1.5 hours) when I already have a young baby in a car. I am going to have to babysit and pay for all of their food and activities.
Also, my nephew doesn't call me on my birthday, so I feel like they just want a free holiday.
AIBU? If not, how do I tell her I can't take him?
