42!
My girl doesn't ask to play chess anymore but we are playing other games like monopoly, labyrinth, we also tried blokus but she doesn't like it much.
Yesterday she was very happy to show me how she can count until 69 (in French numbers between 69 and 99 are special). Then I asked her to tell me a random number.
Her answer was 42! Sweet! So young and she already knows the answer to the ultimate question of life, the universe and everything!
