Some years ago we had a foreign exchange student come to stay, but he didn't want to use our guest room. He preferred to sleep in our pantry...
Fortunately, Eric was very curious and always had plenty of questions.
However, they weren't the kind of questions I had been expecting.
Most of the time I could only say, 'I'm not really sure', or, 'That's just how it is.' I didn't feel very helpful at all.
