No idea, and I don't want to know.
Administrative Note:  This game is about asking stupid questions, and the last several posts here don't strike me as following that theme properly.  I don't consider asking "What's this or that?" as stupid.  It can lead to more problems than anything, which I won't tolerate if it goes into offending others. 

Resuming the game to normal now:  Why is it always harder to go upstairs than downstairs?
