People

Yes, we are all people. You me, even your creepy neighbor that eats cow eyeballs for lunch is a person. And as a person, we all have different personalities. But the question here is, what makes up a "personality"? Is it your preferences ? What you like to wear? What kind of girl/boy you like? But what if someone else, too, has that same liking for turtle neck shirts? What if he or she too likes to suck a spoon full of peanut butter? Or is what makes us different our humanly appearance? Honestly, this has been on my mind for quite a while. What makes a person, a person? Ethan, a Ethan? John, a John?
