I have quite a few people at my school that are like this. I was talking to my friend, and this person who sits close to us is that type of person. I was talking about this book charecter not having friends, and that person was just like "Oh, that's sad." Just out of randomness! My friend got so annoyed at that and to this day he hates that person. So do I. And I was like "You know why that's sad? Because you don't have any either!" I feel so ANGRY NOW!!
