babies are funny (and by that I mean adults are)

I noticed a couple funny things about babies and adults today. The first one is that people will say your baby is cute no matter how ugly it is. What is the official age, or how ugly does a baby have to be, before you can inform somebody that their child isn't cute?
The second funny thing that I noticed about adults and babies is that people always grab the feet or the hands and say, "And how're you doing" as if they think the baby will answer them. I know that they know the baby won't answer, but they do it anyway. That's pretty funny, but what's funnier is that nine times out of ten the parents, knowing their baby won't, answer, "Say, I'm doing fine." It's like they're answering for the kid because they don't want their child to be rude. If somebody asks you a question you answer it, and since the baby can't, the parents do it. It's funny too because they're not really answering the question for the baby, they're telling it what to say, and we already discussed that babies can't talk. How crazy would it be if the kid actually answered? The parents always say that the kid doing well. How do they know? What if he's feeling bloated, or gassy? Then, not only is your child rude, but he's a liar as well. In reality, the baby is probably feeling pissed off because people are asking it questions it can't answer.
