I'll edit that list to my crimes:
When you write fanfic.
When you draw fanart.
When you come up with more fic and art ideas than you have time to write or draw.
When you doodle tenipuri characters in your math notes.

When you have "Koori no Emperor" memorized.
When you have "Koori no Emperor" or other such songs stuck in your head at work, and hum them when no one else is around.
When you listen to Koori no Emperor on an MP3 player and lip sync while dancing... just a little (no srsly, I did once, may be twice).
When you try to get your other friends addicted to tenipuri.
When you actually DO get your other friends addicted to tenipuri.
When a good half of the fics you can recommend to your friends are tenipuri-related.
