(you know your friend Alice very long time, she is your very good friend. for some reason everyone weirdly looks at you when you talk to her, but you never mention it. today, at school, your classmate sat on Alice's place, and Alice disappeared. after lesson, when everyone left, Alice appeared again) she looks a bit annoyed, but still with usual happiness It so annoys when people can't see me, but don't worry, I got used to it
