My wife read some of the Discworld books years ago but lost interest, I have tried to get her hooked for a while.
This morning we collected an old edition of "Alles Sense" (Reaper Man) from the post office. She just wanted to have a quick peak inside. That was an hour ago. I silently retreated to another room.
Now I just heard her shout "I want a curry!" from the living room.
