I had the nickname 'Rue' for a while, since I started a 'new life' after chemo, and have been introducing myself to new people as such ever since. When I came to the realisation that I was trans, I thought, to save trouble with friends getting my new name, I decided to find one that would still have 'Rue' as a shortened version. So, after deliberation, I came up with Ruben, since its not screamingly common, AND I didn't think I was a Rupert. xD So, my friends don't have to change a thing when they call my name. ^^
