For many years, I was known as Firstname Firstlastname, but several years ago I got married and now I’m Firstname Secondlastname. Which is my true label? I tend to go by First, a shortened version of Firstname. Is that my label? Oh yea, also, my wife goes a first name totally different than her legal first name, so her family calls her one thing, and her friends call her something else. She’s still the same person either way. Names aren’t all that important, I’m thinking.
