Angle is the key

A couple strolled around the shopping mall. The woman took a fancy to a set of high-end tableware and insisted on buying it. Her husband was too expensive to pay for it. The shopping guide took a look and whispered to her husband. After hearing this, he thought it was reasonable, so he paid for the tableware happily and bought it home. What made him change immediately? The shopping guide said to the man, "with such expensive tableware, your wife will surely be afraid that you will break the tableware so that you don't have to wash the dishes ."
Enlightenment: there is nothing unchangeable about people's concept. The key is the angle. Be good at figuring out customers' psychology.
