A wife was busy cooking in the kitchen, while her husband kept nagging her from beside her: "Slow down, be careful! The fire is too high. Flip the fish quickly. Scoop it up, you've used too much oil! Flatten the tofu a bit. Oh, the pan is tilted!"
"Please shut up!" the wife snapped. "I know how to cook."
"Of course you do, dear," the husband replied calmly. "I just wanted you to understand how I feel when you chatter incessantly while I am driving."
(Note: Learning to empathize with others is not difficult; it simply requires a willingness to put yourself in their shoes and see things from their perspective.)
