Well, it looks like I am no longer just a brother and a brother in law. According to all sources, my sister is pregnant. As my sister and brother in law appear to have ignored all advice about birth control, it looks like I will be the new uncle of a brand new human being!
Seriously though, I do think this is way cool (except that I now have to spoil this new kid as much as Aunt Dee spoiled me). While the shock of it wore off somewhere on the ski slopes of Central Honshu, I think I can accept this new little tyke into the family. With all due sincereity and joy, I hereby give my official congratulations: おめでとうございます！
