Where would jezis pee?

In the park today LittleE was building a castle. It was a really big castle. You could tell because it had - get this - THREE bathrooms. He remarked that SmallFriendK's house has THREE bathrooms too. Although he's only met her once, SmallFriendK has made quite an impression. According to LittleE, her house has three bathrooms because she has three parents. "Isn't that quite unusual and strange" he asked, "to have a house with THREE bathrooms?"
