Dad and Kell went to an anime convention this weekend. They both attended in costume, which bothered Rudy to no end. It's probably due to his normal 15-year-old discomfort with seeing his mom step out of her role as "mom." (Dad's costuming doesn't bother me. For prey species, changing one's appearance is a natural survival strategy.)
I'm gearing up to return to Beige University, which includes catching up on the research team's advances during the summer. That's why I didn't go to the con, but maybe next year. They apparently have a lot of activities for the nocturnal.
I don't know if I'd dress up; perhaps I'd wear one of those costumes in Dad and Kell's closet that they don't think we know about.
