While "Curt" is not an super unique name, it is fairly rare that I see someone else using it. Most of the time, when I see a variation of that name, they either spell it "Kurt", or they go by "Curtis", so it's different from me (I go by Curt and Curtiss fairly interchangeably). That's why it's really bizarre when I'm reading something and come across that name. I'm reading it like "I don't remember saying/doing that; oh wait, it's not me."
