Rethinking Our Real Estate

Brain cancer is...

 ...rethinking space in our home.

For the past 21 years, the above room has been "the kids' room," and usually two people (in different combinations) lived there. 

We are currently thinking about what to do with it.  Ballroom?  Roller rink?  And what should we name it?  Darrell considered naming it something from the game Clue, but "the conservatory" just doesn't work.  Andi is voting for "the rumpus room," which has such wonderful connotations.

Stay hydrated in this heat, Team D!
