They come to us from the factory completely defective. They can barely open their eyes and all they know how to do is flail around and cry. Even once they learn to hold their oversized heads up, they are still pretty useless when you think about it. It takes forever for them to learn how to do anything for themselves and in the meantime you sacrifice everything--sleep, sex, personal hygiene, brain cells--just so you can wake up again the next day and do it all over again.
But then this miracle happens. Eventually, they stop spitting up on you every time they eat, they finally get potty trained (something kittens learn in a matter of weeks btw), they learn how to talk and provide hours of entertainment. They even learn to chew with their mouths closed. But just when you've got the new-and-improved model--just when they become interesting conversationalists--just the kind of person you love to be around--and friendship looks possible, you have to send them away! It is so not fair.
