Did you name your baby with the intention to shorten the name or use a nickname?
Ie a friend of ours has a felicity but she was always going to be 'flick'. When they did their BA they wrote Felicity (Flick) ...

They don't like her being called felicity.

It makes sense so the child still has a 'proper' name to use. I mean hey, you can't imagine a Flick being elected prime minister can you? Lol

I'm not a fan of long names but don't mind some of them once shortened/nicknamed down.
