Yes. I am a Nerd.

Me: "I found out a few days ago that I am a nerd."

Him: "Huh, it took you that long?"

But it's not a bad thing! Really! I mean look at this definition:

"An intelligent, single-minded expert in a particular technical discipline or profession."

Let us hope we both had that definition in mind, and not this one:

"Foolish or contemptible person who lacks social skills or is boringly studious."
