Self-entertainment
I know this sounds weird, but I can entertain myself for a good hour just by walking around and talking to myself. What I do is make up a game and I imagine my enemies around me and I kill them and stuff, with a nice story-line to go along with it. Sometimes I base my games on games in real life (e.g X-men, Star Wars, COD etc.). I've been doing this since I was a child, but less now. Is this normal?
