There was a sweet city in this cadbury world. There was a boy named Mohan living there. One day Mohan was going to his school by bicycle. On the way he saw an old man was trying to cross the road, but the road was so busy as he could not be able to cross it. When Mohan saw him he became upset as there were many people crossing the road but no one helps him so Mohan came there and helps the old man by holding his one hand and while holding he help the old man to cross the road. Then the old man said to Mohan that "what u want as a gift as you helped me " then Mohan said " nothing ,uncle
just take care of yourself" . As while helping him Mohan became very late for the school. When Mohan came to school he had to stand in the assembly as he was very late. So he was just standing there ,then a man came and said " hey , you why u r standing here" then the teachers tell the man that Mohan was late for the school. Then the man tells the teacher that Mohan was not late , he was just helping him to cross the road. Then Mohan was appreciated by all his teachers and he goes back to his class
