What describe us well? Hmm..... Reflective disk I guess...

Today, after class, I went to Gurney shopping complex with a classmate of mine. We went there by car. This classmate of mine, is the loner of the whole class. And until now, I'm still can't imagine I would actually go out with this classmate. We talked on the way to the shopping complex, and I found out that this classmate is pretty friendly and able to talk easily. We watched movie in the cinema. And this time, we just concentrate on watching the movie without a word. After the movie, this classmate drove me home. In the class, this classmate of mine always avoiding socializing with other classmates: always sitting alone, eat alone and do things alone. And I told myself that this classmate have a lot of similarity like me. Me, dislike socializing, like to do things alone, not so active in outdoors activities and so on. What describes us well, is reflective disk. Whenever I saw this classmate, I would felt like I was looking at myself. My friends all maybe thought that I'm a happy-go-lucky girl, but actually I'm not. This classmate shows my inner self or maybe can say my personality too. I was wandering if this classmate of mine is same like me. Just the opposite way: quiet on the outside, "loud" in the inside.
