My sister invited me for dinner today. She made a delicious chicken and roast potatoes. BIL also invited his 3 sisters who messaged to say they would be 2 hours late so please eat without them which we did.
My sister looks after a 2 years old toddler and works full time. When we sat to eat, my sister said there's more chicken in the oven but this is all the potatoes there were.
My BIL then ate half the potatoes (like at least 8 full potatoes), the rest of us took 1 potatoes each as we could see there was not a lot, then BIL insisted my sister make a fresh batch of potatoes for his sisters when they come.
This really annoyed me as my sister is busy and tired and he could have just eaten less but he thought it was appropriate to eat way more then make my sister make more when she was already tired. Also why didn't he just make more.
AIBU?
