A little boy and his father visited a country store. The dad picked up a few things and went over to pay for them. The owner of the store said to the little boy,
“Grab a handful of sweets.”.
The boy just stood there looking up at his father.
The owner repeated, “Son, grab a handful of sweets… they’re free.”

Again the boy didn’t move.
Finally the father reached into the candy jar, took a handful of sweets and gave them to his son.
As they walked back home, the father asked his son why he wouldn’t take a handful of the free candy.
“Because,” the boy answered, “your hand is bigger than mine.”
