"... the advantages of being a postman seemed more and more dubious. It is not a congenial profession for anyone who is at all sensitive, for people visit upon the postman all their first annoyance at receiving a couple of bills when they looked for a love-letter, and if a packet is insufficiently stamped they hand over the pennies as though to a despicable bandit, too outrageous to be denied, too groveling to be feared."
