Don’t want to celebrate my Bday

So this is long....

Tonight I went out with my brother: who I’ll call 1, and my other brother: called 2, my mum, my dad and 1’s girlfriend. We out to dinner. I don’t like dining with my family because I always get left out of conversations and get rly bored. Tonight my family were talking about 1’s future. I tried to say something and my mum said “we’re talking about 1.” This made me a bit annoyed because I think my mum favours him often.

To add on top of that the food was bad but that’s not relevant. 😂

It may seem childish but this makes me not want to celebrate my birthday. It’s a tradition in my family to go out for a meal, but I don’t want to go out because I know I won’t be included anyway and I’d rather stay home. I never have birthday parties so that doesn’t matter to me. I wasn’t planning on telling people at school about it anyway.

Am I being childish and moody? Or is it justified?

I know my mum will get annoyed and call me moody if I say I don’t want to go out.

Is she right?
