Never spy on Erik when he is bathing.
Never play with Erik's Punjab lasso.

You must never climb into the coffin while Erik is sleeping.
You must never use the coffin as a floating device.
Auctioning off the swan bed on E-Bay so that you can sleep in the coffin with Erik seems like a very good idea. It's not. Never do it.

Reading Erik/Raoul slash out loud is unacceptable and often fatal.
When about to sail through the underground lake with Erik, it is very inappropriate, no matter how tempting, to shout, "Save the gondola! Ride the Phantom!" … I know from experience. NEVER do it.
Telling Erik that black is a sign of sexual desire, and then saying coquettishly, "Hmm…you must be famished," while running fingers up his arm, will not end as blissfully as hoped. Don't even try.
When telling Erik about "Operation: Fop, Meet My Cheese grater", you must never let slip about "Operation: Christine, Meet My Baseball Bat." It will hurt.
You must never play with Erik's dolls.

You must never, ever glomp Erik when he is composing. Or ever. : (

You should not compare Erik to Severus Snape, Gríma Wormtongue, or any other lurk-happy, creepy guy from any other novel.
You must never put a large sign on Erik's back that reads 'Trademark to Gaston Leroux, re-trademarked to Andrew Lloyd Webber.' He will not appreciate it – plus, it's extremely difficult to hide in the shadows when you have a large white piece of paper stuck to your predominantly black outfit.
You should not call Erik 'Mr. Twirly-cloak-O-Doom', 'Mr. Dramatic-Exit-O-Doom', or 'Mr. Loom-O-Doom'. Or 'Mr. Falling-Chandelier-O-Doom', either.

Don't use the coffin as a flotation device.

Don't ever hum the Jeopardy theme whilst Erik is thinking.
Never pee in the underground lake.
You may not ask Erik if he knows the muffin man.
You may not ask Erik if he is the muffin man.

Refrain from calling Erik Michael Jackson.
Don't ask him if his lover is Billie jean and if the kid is his son.
No matter how cool it would be, you must not install a killer sound system in Erik's lair. If I do, he will proceed to show me just how killer it is.
