Maybe these things make sense when you're a mom.
First scenerio: All three of us were playing a board game (kiddie scrabble). You have 7 tiles, you play 2 and then pick up 2 for a total of 7. We have played this game 3 times in the past three days. About 15 minutes into the third game, Allison looks at me when it's her turn and declares, "I don't remember how to play!"
Second scenerio: Victor and I were playing a game. I finished my turn. Victor looks at me and asks (very seriously), "Is it my turn?"
