here was a big surprise waiting for Maqsud when he came
home from school. His father had bought him a little kitten.
Maqsud would spend the time left over after doing his homework
playing with his cute little kitten. One night, when he was in bed,
he was surprised to see the kitten leave the bedroom and find the
milk dish in the pitch-dark living room.

through our retinas twice. That is
