I go by my middle name and most people I meet wouldn't know it. When I first started dating my wife she probably didn't know my first name for several months or more. Its not like I intentionally don't tell people that I go by my middle name, you just forget and don't think about it just like most people probably don't think about their middle name that often until it comes up. Most of the time it comes up in conversation when a friend asks what my middle name is, and then I have to explain it. I prefer my middle name thats why I choose to go by it, but my parents called me by my middle name since I was born. It is a tradition in my family, all the men go by their middle names.
