Though she was old she wasn't by any means incapable of supporting herself; and at the fresh, youthful age of seventy-nine she went into the business of providing teas for perspiring cyclists, and storing the cycles of those travellers who decided that they had better return by train. Her first customers were four young men who left their cycles in her charge while they explored the neighborhood. For each cycle she gave them a ticket with a number upon it.
Late at night the tourists returned.
The old woman led them to their cycles with a smile of self-satisfaction on her face.
You'll know which is which, she told them, "because I've fastened duplicate tickets on them."
They gratefully thanked her; and when they found their cycles they discovered that the tickets were neatly pinned into each back tire!
