"That makes a dollar, son. That's a whole lot of money for a boy only five years old."
That set Bobby to wondering.
"Is it lots of money for a little boy with seven birthdays?" he asked.
"You can just bet your boots it is. A boy can buy all sorts of things with a dollar."
As he spoke, the man pulled a great, round white piece of money out of his pocket, thereby revealing to Bobby that his pockets contained other things besides quarters, and making him forget that four quarters is an awful lot of money even for a boy with seven birthdays.
"Know what this is?" asked the man.
"Money," replied Bobby.
"How much money?"
"A grown-up quarter," hazarded Bobby at length.
