That... Might be a little tough but I wish you good luck!
you are underestimating the chillness of my parents, their reaction is basically *shrug* "it's your choice"
(which is incidentally the same answer as two years ago, when I found that my great-grandmother's name was Eleanor and I jokingly asked why they couldn't name me that instead of Helen)
BUT
while changing my first name here in norway would be some hassle in changing legal documents like passport and credit card and all that... it would still be even more hassle with my czech citizenship. they have a bit stricter rules and I would have to ask permission before I changed and then go through the whole id card ordeal again.
but what I can do to avoid Most of the hassle
is to add it as a middle name
and I really think I'm gonna do that
*jumps up and down*
