Luck
Cycler (passing a carriage on the road):—“And still there are cabs—to-day, when the cycle rules the world! They are a funny sight!... Of course an old woman is in it; who else would use one of those antediluvian vehicles?”
(Half an hour later, he and his wheel have been picked up by the occupant of that carriage, both badly bruised and battered):—“What luck, that this cab came along! I wonder how I would have gotten home without it!”
