chained_bear Sionnach, I responded to this comment on your other comment on my profile. If in fact you haven't gone away yet, you might see it there. Hope tax season treats you kindly. Mar 9, 2008
sionnach Ya know, I'm in complete agreement with Stephen on this point. A good novel is a fine thing. But a little nutmeg goes a long, long way. if I want to read this book, presumably I have the option of buying it for myself. Being forcefed huge chunks of it whenever I log in to Wordie is not actually my idea of a good time.
Yeah, I'm grumpy. It's tax preparation time. I'm going away until I can manage to be more civil. But c_b, please have mercy. oh, never mind. It's a free country.
