     The bus station, a street corner in the city, the caf ? at the mall… American teenagers like to hang out

at these places.

     I want to tell you this is true. American teenagers have far too much time to waste (浪费). Because

they have short school days and their parents are busy at work day and night, US teenagers find happiness

in doing nothing.

     "What do you do all day in that park?" A mother will ask her son or daughter, with some reason. "I

don't know, just hang out," her child might answer.

     Of course, some kids keep busy with after-school sports, test-prep (测验准备) classes and clubs. I

did some of these activities, too, but still found time to hang out in the park. For hours, my friends and I

would sit on the stairs talking, playing games, or just watching the cars drive by … doing nothing.

     Was it all a waste of time? Were we up to "no-good"? Maybe. When I think about it now, I can't

believe I had so much free time as a teenager! Now, I should spend any free moment at the gym (健身房), writing a story or learning a new language. It seems uninteresting, but I do miss "hanging out".
