Things I have always wondered about

There are a few things I still wonder about in my "old age". I wonder who closes the door when the bus driver gets off? If the prince climbed up Rapunzel's hair, how did they both get back down? What exactly makes Jello solid and why doesn't it melt once it's set? If people who have a ton of children are said to breed like rabbits, then do people who have very few children breed like elephants? Why do we save the whales but exterminate the termites, roaches, and ants? Is it that size matters or the number of legs and cute quality of the species? Why is no mouse flavored cat food? Why not have a mailman flavored dog food? I mean, they go after them anyway, so why not nip it in the bud? If God was so good at creating things, then why did he make so may bugs and not enough mammals? If he could make birds fly, why couldn't he make pigs? And if man was suppose to be the most intelligent species created by God, WHY DO WE HAVE TO LEARN FROM OUR MISTAKES? I really don't claim to have all the answers, but sometimes these things keep me awake at night. I guess I'm just weird, but if anyone could answer that Jello question it would really take a load off my mind.
