I have an email from my mother in which she says "I am going to be a Great Granny".
To the best of my knowledge I'm not a parent, and I believe this leaves me in no danger of becoming a grandparent. I'm assuming this means I'm going to become a great-uncle of some sort. There aren't any clues in her email which might help me identify the source of this change of status, but I'm sure I'll find out in due course.
Erm. Woo hoo, or something.
