You hear the phrase Like father, like son all the time, but what about the rest of the people in your family? My sister, Sarah, and I are the most alike out of our family. But what makes a person so alike to another? Is it something hereditary that is passed down from person to person to make people in your family so alike? Or so different? I think that's all a lot of superstition. No one in my family is the same. We're completley and totally all different, which is a weird, but beautiful thing. Haha. The only resemblence me and Sarah have is maybe our hair color even though mine is a bit lighter. Ah, but all well. Life is about variety right?
