I feel like introducing this woman to the story of two of my mom's unmarried sisters. Up until a couple of years ago, when the youngest decided she wanted her own room in the family house, they shared a room in all the places they lived together. They're in their seventies, and they still have a shared room in the three-bedroom apartment where they live by themselves half of the year.

The idea that if two kids are 4 years apart they won't want to share a room is hilarious too. I'm convinced that the only reason my sisters (1.5 and 5.5 years younger than me) aren't still sharing the same room is because my parents stole the big one for themselves when the oldest went away for a year. A very nice room too, I didn't mind sharing it with them until I was 12; having all your kids sleep in the same room is great for bed-time reading aloud!
