We played 2 games last night - Takenoko and Dixit (which I described here and here).
In Takenoko, my wife raced out to a big lead; she looked like she would win handily. I was in last place for much of the game, then slowly accumulated points, and near the end of the game had nearly caught up. In the last turn, I was able to complete an objective worth 5 points, which allowed me to pass my wife and win the game.
In our second game, Dixit, I raced out to a big lead. My wife was in last place for much of the game, then slowly . . . Hey, this is sounding familiar. Yep, this time she pulled off the comeback and stole the victory from me. I guess turnaround is fair play.
