Just while you're deciding what to do, you hear a loud bang. Spinning around, you see the front door has slammed shut. You try to open it, but it's locked tight, and won't budge no matter how hard you pull. Concerned at this latest development, you spin round to see if the back door is locked. That's when you notice a piece of paper on a table next to the living room door that wasn't there before. Picking it up, you start to read:
"Congratulations! You are the 10000th person to visit Ivory Mansion! That means the house is now yours! You may have noticed that everything may not be the right size for you at the moment. By sealing you inside the house to avoid calibration issues, this will be adjusted over the next few hours. In the mean time, relax! Everything functions normally, so sit back and watch some TV or listen to some music while you find the house more and more appropriately sized for you."
A free mansion, that will shrink down to the appropriate size for you? Sweet! Funny way to have won it, but you don't look a gift horse in the mouth. Or gift elephant, if the picture in the hall is to be believed.
