Nightwing has 13 because he is stern and venerable.
Wow, live long enough and people call you all kinds of things!
I think I should feel flattered, but instead I just feel old. "Stern" sure beats "curmudgeonly," but no matter how you slice it, "venerable" makes me sound like that wizened old teacher in "Kung-Fu," telling Grasshopper to snatch the pebble from my hand.
Actually, that reference alone probably confirms my advanced years, doesn't it? Sigh...
Anyway, I retract my objections to the points system. If I'd known I'd end up in the "popular" crowd, I'd never have made a stink. You like me! You really like me!
(Aaaaaaaaand the points begin to tick to the negative...)
