Andi-O: Hope you get this as I'm noodling around on the net right now. Just realized i totally misread that you were "XX" and that Means I'm also "XX" (unfortunately, it took a male science-oriented pal to straighten me out on this point) and therefore you don't need to "be a good dad" at any point in your career either. Again, hope you get this and the points I tried to make earlier are still worthy despite my ignorance of basic genetics! I tried! Who can condemn a formerly "silly and ignorant" female (Austen)? Amy
