@Indigo @dielan On a semi-related note, and it may sound weird, but I don't like people knowing my last name even IRL. I don't feel like it's important and I went to keep family stuff private, but if someone knows me because of someone that I'm related to, then I'm going to be known by a first and last name basis and be called by both my first and last name.
I hate last names. They're actually a recent invention. We went well fine without them. Hell, people in Iceland do use them that much.
They're almost never called me by my first name for anything other then legal reasons, I consider the name I go by to be my "real" name.
