Have you ever received a gift that was so clearly not your taste? Worse, have you ever given a present and watched your friend look as though she had opened the wrong box? 小题1:__________? And what do your choices tell about your personal qualities(品质)? 小题2:__________. It calls for empathy—the ability to put yourself into someone else’s head and heart. We’re all able to do this; in fact, we’re born with a kind of natural empathy. 小题3:__________. When it isn’t, we’re not able to understand other people’s feelings sharply.

Passing over the tradition won’t make it go away. 小题4:__________, tell your friends ahead of time.
