Mr Smith had two sons.One was seven years old, and the other was five.One morning during the holiday, when Mr Smith was cleaning the car, his younger son came and asked him for some money for sweets.

‘Sweets are bad for your teeth,’ Mr Smith said.‘Take these two oranges instead, and give one to your brother.’

One orange was much bigger than the other, and as the small boy likes oranges very much, he kept the bigger one for himself, and gave his brother the smaller one.When the other boy saw that, he said, ’It’s selfish to take the bigger for yourself.If Father had given me the oranges, I’d have given you the bigger one.’

‘I know you would,’ answered his brother.‘That’s why I took it.’
