Us: So, where are you coming from?
Us: Oh! Business or pleasure?
Them: We attended a convention.
Us: *blinks* Ummm...Let me guess...Mensa?
Them: *blinks* Yes! How did you know?
Us: *grins* Oh, we were at the OTHER convention!
Them: *smiles* Oh! You're furries!
I guess my Confurence '03 shirt also gave that away. We then had a great conversation about the fandom and their organization, our ties to the sci-fi community on both ends, overall geekyness, and how the convention system works for both groups. The husband was most intrigued with fursuits. He wanted to know the most unusual creatures out there. Manticore, cuddlefish, and purple furry-eater were at the top of the list. He also gave us an idea for a great schtick for a con; a blind dog with a seeing-eye human.
