When my brother, a notorious spender, came home for a visit, he told my father he was going to get married and settle down. Dad said, "Why don't you stay single and settle up."
我的哥哥是个有名的挥霍者。他回家来时,告诉父亲说他要结婚了,要安定下来。父亲说:“你为什么不实行独身主义,先把欠债还清呢?” 注:settle down是“安定下来”,而settle up 是“还清欠债”意思,二者虽只是up与 down不同,但意思却完全不同。
