Driving through the hill country of Texas，just north of San Antonio，we watched the sky turn a brilliant orange at sunset. At my wife's pleading，we stopped and walked up a hill，which turned out to be the top of a cliff. Before us lay the picturesque postcard setting we had been looking for
during all our vacation. Below was a large green valley circled by hills. Exhilarated by the tangerine sky, long shadows，and a slight breeze carrying the scent of green grass，my wife suddenly shouted:“Thank you，Mother Nature，for so much beautyl”
Then, a distant voice was heard from across the valley:"No charge!”
Early one morning, my next-door neighbor set to work with a power hedge-trimmer. He was half through the job when a neighbor appeared，still in his pajamas. He was carrying his own power clipper and offered his help, which was gratefully accepted. When the job was done, my neighbor thanked his benefactor，commenting that it had been "a real neighborly act".
"Don't mention it，“replied the other man. "I figured,by helping you，it would only take half as long and I could get back to sleep!"
Although my mother，a native of Japan, has lived for 55 years in the United States，she has not adapted complete1y to the cultural change. This is especiallly obvious during her infrequent forays into a large city.
One day she boarded a bus in Los Angeles，deposited a $5 bill in the coin box and held out her hand for change.Because the coin box is not built to accept paper money，the bus driver growled:“Okay，lady. If you get that bill out,you can ride for free. Otherwise we're going to have to dis-mantle this coin box."
My mother hesitated but a moment, then opened her purse，took out a pair of chopsticks，retrieved the bill and smiled as she took her seat.
