Of course, it doesn't have to be 'Lucy Melford'. It's my life, my identity, and perhaps I should reconsider.
'Lucy' does in fact have some of the sounds of my old first name, especially the 'oo'. It also carries the notion of 'light', which is very appropriate for a person who snaps away with her camera a lot. Perhaps then I should go Greek and call myself 'Phota'. Then it could be something like 'Phota McFloater', or 'Phota Phinnish'. Hmmm. Something unnatural about those names.
On balance it seems best to stick to what I've been calling myself for the last ten months!
Aren't trans people privileged, to be able to change their name to something entirely their own choice, for a cast-iron reason that nobody can argue about? One of the nicer things that happen along the way.
