When my daughter was born I registered her in the hospital, where the registrar came round to the bedside. We gave her the middle name "Tanja". When the birth certificate came through it had named her "Jamjar". I really felt I couldn't have her going through life called Jamjar so I sent it back!! But she was affectionately called Jamjar for a few weeks after that.
I don't want to be the one to mention this, but there seems to be a bit of a pattern emerging here of a certain gender failing to follow instructions!
