Reading mnemeion's journal

It's really hard to explain it, but I like being alone. When I say to my friends that I like being alone, and I like being sad, the reaction I'd get is laughter. It's really hard to talk to people beneath your understanding of things.
Nostalgia, that is the honey that makes me go into my room and stay there for a week. Is that a problem? Is there anything wrong with that? I don't reminisce my past, but the feeling of being nostalgic is what I really desire. When I'm sad, I feel that I badly need someone to talk to, or be with. Then I'd go lie down on our roof under the stars, then I'd feel happy again. Anyway, that's my first journal, so forgive my nonesense.
