conversations.value: Eric spent 2 hours removing wallpaper from just 1 wall of his 4 walled dining room.  He also needs to remove wallpaper from his 4 walled living room.  How many hours will it take him to remove the remaining wallpaper?
conversations.from: assistant
conversations.value: His dining room is 4 walls and he has already removed 1 wall of wallpaper so that leaves 4-1 = 3 walls in the dining room
  He has 3 walls left in the dining room and 4 in his living room for a total of 3+4 = 7 walls
  It takes 2 hours to remove wallpaper from just 1 wall and he has 7 more to go so it will take him 2*7 = 14 hours
