Today I received a letter from the bank:

Bear in mind that in order to get a French bank account I needed a lot of paperwork. I had to give them a photocopy of my passport, my contract of employment, previous bills, etc, etc… and in all of these documents my name is clearly written in full: Christopher

I suppose an inevitability of moving to France was that I’d become Christophe. I just thought it would happen later rather than sooner.
