I love your post! why? Because during my school times I always changed my name, because I could not identify with my birthname and I had the feeling, that one name is not enough. I chose names from books or music I loved and with every new teacher I told them this new name. They used it up to the next parent-teacher conference, then the fun stopped.
I love to get (nice or funny) nicknames up to date, but I also experienced the ugly side of naming. And I think being called something negative (or with a negative attitude.) Some people called me "Aphrodite" which does not sound hurtful at the first glance, but they named me so, because I looked like the opposite of a Greek sexy goddess: means I had no womanly body, no breasts combined with red hear and a very big nose. While writing it down, it sounds so weak on my side, because there are so much more negative things you could be called - but these people really hated me, and I felt excluded. I think this name calling is so hurtful, because someone is trying to define you and tries to erase (ok, many this is a little exaggerated) your self and self-confidence and everybody can hear it.
So, thank you for this post. I think names and how they define the world is a important topic <3
