Yaaaay! ^____^ I like making people smile. It's a lot better than the alternative. (Though I have to admit that I'm also guiltily pleased when people tell me that the sad stories hit like a punch too, on account of that means the fic did its job, but yeah, smiles are better.)
I've never had a dog, but my grandma did, and sometimes it got so into the tail-wagging it knocked itself over. And then there's my neighbors' parents' huuuuuuuuuge black Lab -- 120 lbs of sheer adoration in dogshape, with a tail that means anything below hip-height is no longer safe from imminent destruction. XD I suspect that on the morning after they've had to replace the two dozenth table lamp or so, Seph starts contemplating how to turn Zack's tail into a deliberately lethal weapon on the combat field rather than just an unintentionally lethal weapon for their home furnishings. XD
