Why are we attracted to who we are attracted too?

Human attraction is a very unexplainable. You ask someone to describe what kind of person they would like to be attracted too and they will tell you physical things. They might say that the person needs to be blond or tall. They might also say that they should have blue eyes or hazel. But is that what being attracted to someone is all about. I don't think that is the case. I think that being attracted to someone whether that person is a boyfriend, girlfriend, or just a friend is more. There has to be a deeper connection for it to be a true connection. Sadly many times we fail to understand that we need to look beyond the skin beyond what we see can we see the beauty before us. That is what we can truly love and care. That is a true attraction or connection.
