@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.
