There are several people I've known for years and yet have zero ability to pull up their name. I think at this point it's an accepted part of their identity. On the other hand, I've also been known as "David" by someone else. My name isn't David, but since I didn't correct them the first time, I'm forever David when that person visits. Let's hope Specialist Yarn manages to catch somebody's name being used in conversation. It would certainly be a shame if everyone else was aware he'd forgotten their names but was too shy to ask and were intentionally avoiding using their own names. That really would be such a shame.
