When my grandmother was raising me in Stamps，Arkansas，she had a particular routine(惯例)when people who were known to be whiners entered her store. My grandmother would ask the customer，“How are you doing today，Thomas？” The person would reply，“Not so good today, Henderson.You see，it’s this summer heat.I just hate it.It just makes me tired.It’s almost killing me.”Then my grandmother would stand calmly，her arms folded，and say，“Uh-huh，uh huh.”
As soon as the complainer was out of the store，my grandmother would call me to stand in front of her.Then she would say the same thing she had said at least a thousand times，it seemed to me.“Jane，did you hear what so-and-so complained about？”And I would nod.Grandmother would continue，“Jane，there are people who went to sleep all over the world last night，poor and rich and black and white，but they will never wake again.Those dead people would give anything，anything at all for just five minutes of this weather that person was complaining about.So you watch yourself about complaining，Jane.What you’re supposed to do when you don’t like a thing is change it.If you can’t change it，change the way you think about it.Don’t complain.”
I have learned a lot from my grandmother.Her opinions always hit the nail on the head.Whining is not only impolite, but can be dangerous.
