AIBU to hate people giving my daughters nicknames?

[thatblue]

I have twin DD's who are 6. Their names are Francesca and Harriet. I absolutely adore their names, and couldn't imagine ever shortening them. I had parents evening tonight and had to tell the teacher multiple times that their names are Francesca and Harriet, not Frankie and Harry. Nothing against anyone who does shorten those names, I just think the names are beautiful, and I'm not keen on the shortened versions. Turns out they even had the nicknames written on some of their books!

AIBU to tell the teacher to just politely tell them to use their full names, or should I just accept defeat and let them go by the shorter names? The girls said they aren't overly bothered.

I think both Francesca and Harriet are fabulous names, in part because there are so many options for shortening them!

Francesca could go by her full name or Frank, Frankie, Fran, Franny, Cesca, Chessie or Chess. Harriet could use her full name or be Harrie/y, Hattie, Hat, Hats or Ettie.

My DDs have names of similar lengths and are known by shortened versions, including by their teachers - they usually tell their teachers in September what they'd like to be known as and have been doing so since nursery.

"My MIL insists on calling my daughter Lils (Lily). I politely remind her that her name is Lily"

So he grandmother calls her an affectionate pet name and you "politely remind her" not to? Blimey.
