In my school-days, when I had lost one shaft, I shot his fellow of the self-same flight The self-same way with more advised watch, To find the other forth, and by adventuring both I oft found both: I urge this childhood proof, Because what follows is pure innocence. I owe you much, and, like a wilful youth, That which I owe is lost; but if you please To shoot another arrow that self way Which you did shoot the first, I do not doubt, As I will watch the aim, or to find both Or bring your latter hazard back again And thankfully rest debtor for the first. From The Merchant of Venice.
