Thinking about this since I just found out a friend of mine didn't know, but I have 2 first names. I only use my first first name, so people think my second first name is my middle name. It's not. I have no middle name. I just have a first first name and a second first name like [name]-[name] (note the dash. The "-" is very important). I also have a friend with four middle names. She refuses to share.
