“There's no good reason why this boy should not pay the bill if he wants to.”
“No, I suppose not. But I don't believe he was so keen to get into the world as all that.”
“Well, it wouldn't surprise me much if that young fellow should come into my office one of these days and offer to settle that old score now that he knows about it.”
“Don't you take it if he does!” and Mary left the room quite unconscious that her pronoun was without an antecedent.
Ting-a-ling-ling-ling-ling-ling.
