My mum and my sister both share the same birthday in December. This year my mum is going to 60 and my sister will be 29.
Every year, my mum has taken a back seat on her birthday so my sister got all the fuss etc and my mum never ever complained about this, she was always happy for my sister to take center stage on their birthday.
This year we have decided to take mum out for a nice meal as it is her 60th, so as it's in December (Chistmas parties etc) we have had to book the table now.
So yesterday, my sister phoned my mum to say she and her partner weren't going to be coming because she has decided to go for a meal with just her and him to celebrate HER birthday.
I think she is being selfish. She can celebrate her birthday with mum at the meal with all of us, i think it's just because she won't be center stage as it's my mums 60th.
Next year she gets the big birthday being 30! She has annoyed me alot. I haven't heard from her yet to tell me she isn't coming and i am unsure what to say to her when she does?
