I was named Annabel after my great grandmother, Annabelle. My mother didn't love the name so she took away an 'l' and an 'e' at the end. She thought the original name was a good one for the family cow, the one you keep out the back for your every dairy need.
Everybody called me Anna until I was 13. I even remember talking about my name to my teacher when I was 5 - I thought the 'bel' part was a middle name, giving me two middle names. On my first day of high school, my form room (home room) teacher asked me what I wanted to be called and I announced to the world that I had always been called Anna but I preferred Annabel.
Most of the world didn't hear this and continued to call me Anna well into my 20s, no matter how many times I asked to be called Annabel. I think I'd always said when asked: "My family call me Anna but I really prefer Annabel" When I moved to Bangladesh, I didn't mention the Anna bit and I was firmly Annabel. It works much better than my first approach.
Just before I went home last November, I sent a rather abrupt, almost shocking, email to my immediate family, who fail time and again to introduce me as Annabel. I basically shouted at them over the interweb: I AM ANNABEL, NOT ANNA, PLEASE STOP CALLING ME THAT. It all arose from nerves about travel, the tension that comes with planning weddings, and feeling so disconnected over here, on the other side of nowhere.
It worked, I even got a few apologies and explanations. On my visit home I was clearly introduced as Anna... bel (with a little pause, as they remembered). I love you, family! Thanks for breaking an old habit for me. xx
