Very sad for you. My parents were fairly sharp, decent and considerate people. They had seven of us and took us everywhere they went. Screaming and misbehaving at a restaurant, even as toddlers, would have been no more tolerated than it would have been at home. And as babies, we either slept or ate... very little fussing, and quickly removed if we did. We're the same with our son. Some people really do have good babies. It has to do with bonding with them early and often, and not "sticking" them in daycare so they don't even know where they are or who they're with half the time.
As for the dog, I completely understand - but you, unfortunately, haven't the compassion or experience to say the same re kids. We have two furry babies who are actually more work than the boy what with grooming and exercise etc. The baby learned how to say "sit" and "stay" before he learned to say "Mommy."
