When I was 28，I was teaching English to high school freshmen in a schools where occasionally the faculty and staff were allowed to dress down.
28岁那年，我在一所高中教一年级学生英语。这所学校允许教职员工有时不必穿得那么正式。
One of those days, I donned a sweatshirt and slacks. A student came in and his eyes widened.
一天，我穿了一件运动衫和一条休闲裤。一个学生进来看见后，看着我瞪大了眼睛。
"Wow!” He exclaimed. "You should wear clothes like that everyday. You look twenty, maybe even thirty years younger”
“哇哦!”他大呼小叫地说:“你该天天都这么穿。你看上去足足年轻了20岁，甚至30岁呢!”
