My mum and her side of the family is very posh, my dad bought us up so I didn't live with her growing up.
I grew up on a council estate and went to a rough state school so I always felt embarrassed at the fact my mum wanted us to call her mummy, I started calling my dad, dad when I was about 16.
When I write to her I write dear mum but she signs letters off from mummy and it makes me shudder.
AIBU to find this all really awkward (I'm 29!)
