She thinks its ridiculous. Looks and personality wise, she is somewhere between Kate Winslet and Sue Sylvester from Glee, with a Hull accent. She hates the way that whenever she tells anyone her name, they say 'Annabel?' as they struggle to reconcile their preconceptions with the person stood before them.
Even as a child, she hated it. When she moved to secondary school she tried to change it, and we had people ringing up asking for Annie.
The plus side is that no one ever forgets it, and when she addressed conferences, she is the one speaker every one remembers.
As the big sister, and the one who, according to family legend, chose the name Annabel, I still think its funny she is called Annabel. I forget about it for a while, and don't notice it, and then something will make me become aware of it, and it will make me laugh. I'm smiling now.
