Every moment of Lily's life?
There hasn't been any sharp decrease of intelligence at a specific point, but rather, one of ignorance. ^^;
When I was little, I walked in front of a girl who was high up on the swings. Inevitably, I was kicked in the eye by her foot. Not long after that, during my dad and his brother's tennis match, I ran toward the middle of the court to pick up the ball, but (inevitably) got hit in the same eye by a serve.
We went to an amusement park, and my relatives found it amusing enough to place me inside a robot, which was meant for small toddlers. I acted bored, because in those days nonchalance was considered cool, and tried to get out, but (inevitably) twisted my arm and nearly broke half my body, since the robot was automatic and kept going round and round...adults were staring and pointing. ;;
I also liked someone and trailed him 24/7, only to realize he was infatuated with my best friend. x_x
