Let me tell you what happens when you bring home a three-legged dog: People think you're friggin' crazy. Or maybe Mother Theresa, reincarnated. (Sorry, God, that was probably, well, not blasphemous, but hopefully not hell-worthy, since I'm not Catholic, and I'm almost certain Catholics don't reincarnate. If they did, it probably wouldn't be into a Presbyterian. Yeah, tangent.)
Anyway, I've spent the last seven months trying to convince My Sister the Lawyer that someday, if I adopt children, chances are good they won't have three legs.
Can you just imagine trying to find jeans for that kid?
(True: It is okay to put your dog on a leash. For some reason, it's also more or less socially acceptable to leash your children. It's less acceptable to leash friends and lovers--keep that behind closed doors, please. Leashing a subordinate at work will probably get you fired and/or sued.)
