Because Kitten couldn't stop playing with the earthworms in the parking lot of our apartment. It rained last night and they were crawling everywhere. She was delighted. "Here wormie! Come here, little wormie!" she called to them as she clapped her hands at them. She tried to touch one and recoiled in horror, as did the worm. "He's so cute!" she cried.
Then I felt really bad as we drove away, knowing that I was probably running over some of her new friends.
