As title says.
Me and my brothers don't have the best relationship although I try and get along with them for my mum. Today was my mums birthday and I planned a meal out with her and both brothers, my youngest brother is in a relationship with a woman and she has a 5 year old DS. She's only been with my brother for 9 months but she's already Introduced him to my brother and my mum has also met him.
One brother couldn't come but my younger one said he could but he'd brought his girlfriend's son along. He said the child had been sick last night so he couldn't go to his activity and his mum had to work so he was looking after him. All throughout the meal the child kept getting up and was being a typical child at a restaurant. We then were going to go back to my mums but brother made a comment about them going back to his girlfriends as the child still had an upset stomach but says it isn't a bug.
AIBU in being annoyed?
