Yes, all their name stuff is a bit weird, sort of a way of remaining detached emotionally, or maybe I'm going too deep.Why does eveyone call Dianne, Nanny Di? Do the girls call Nadia's parents, grandpa Teddy? or Nanny Bobbie? If the grandchildren address them simply by their first names, I find that is the ultimate sign of disrespect. I am sure their other grandchildren (Dina's children) probably address Dina and Nadia's parents correctly as grandfather and grandmother. The other thing I always remember is Dianne is 70 years old and Nadia is 56 years old, only 14 years between them, but Nadia still insists on calling her Nanny Di, even when the poor woman is right infront of her and she is directly having a conversation with her !! Nadia's dad is 85 years old ..........25years difference between him and Mark but only 15 years between him and Dianne, ........ so maybe Dianne and Mark should follow Nadia's example start calling him "Granpa Nads" or "Grandpa Ted"
I suppose it's like having a nickname. Always wondered why they call her Dad Teddy, and on Wikipedia her Mum is called Roberta yet they call her Betty and then Dina is, Dina
