Regret

This door is next to the bathroom in second floor of the Mansion.  The plaque on the door has one word on it: REGRET.

Everything in this room is made out to you.

The trophies have your name on them.  The pictures in the photo album show you as a child prodigy, smarter than anyone else, by far.  Your lovers are the most desirable members of the opposite sex.  The newspaper clippings show you to be the best at whatever you did.  You never backed down, you never lost, you always made your loved ones proud.

Everything in this room crumbles soon after being touched.  The smell of the dust makes you gag.
