Zman was packing to go on a 4 day photographic journey, and the McKid was sitting on his bed "helping" him get ready, as only a 5 year old can "help". Zman is so good to her, but he is forever making up stuff to tell her, to see if he can get her to believe it. They're chatting away in his room, while I'm here in the office.
All of a sudden, there's an indignant 5 year old voice:
McKid: MOOOOOOOM! Is Zack invisible?
Me: I don't know. Can you still see him?
Me: Then I guess he's not invisible.
Hmmmmm. Go figure.
