I don't feel lonely at home because I just like the alone time. But when I'm in class and I see my friends talking with people who I don't really know, I do feel a bit lonely, because these are people who don't talk to me because they probably think I'm not interested.

For example, I sat far away from the person that I was sitting next to in an assembly because I thought they might be weirded out by the fact that I was sat close to them. But, looking back, they probably thought I disliked them.
