i knew i was a silly student, but my parents always believed that i would be as clever as newton. therefore, they tried all means to make me more clever.
one day they asked me to go and stand under a big tree. i was reading a difficult math book there. suddenly i heard a strange sound. someone was there.
when i was about to see who was there,i felt something hit my head. it was an apple! more and more apple fell off from the tree.
