One of the best parts of being a parent is figuring out what kind of person your kid is going to be. Some parents claim that their babies come out of the womb exactly the way they're going to be as adults. If you come out screaming, then you're going to continue screaming into adulthood. If you come out quiet as a mouse, then chances are you're going to carry that calm with you. I'm not sure if this is a load of phooey or not, but there has to be some truth to it.
Kids have huge personalities, and some of them barely change. This is of course the whole question of nature vs. nurture. I remember meeting my best friend when we were 6 and 7 years old. We're lucky enough to be best friends decades later, and we're still the same at our core. Sure, we have more experiences to draw on, but we're still those same little dorks. Enjoy these parenting tweets while you mull over the question.
