Have you ever had an embarrassing (尴尬的) experience? Last week we asked readers to tell us

Have you ever had an embarrassing (尴尬的) experience? Last week we asked readers to tell us about embarrassing experiences. We received thousands of letters! Here is a selection.
Tony: My most embarrassing experience happened when I had just left university. I had just started teaching in a Liverpool secondary school. One morning my alarm clock didn’t ring. I woke up at half past eight and school began at nine. I quickly washed, dressed, jumped into my car and rushed to school. When I arrived, the students had already gone into class. I didn’t go to the office, but went straight into class. After two or three minutes the students began laughing, and I couldn’t understand why! Suddenly I looked down and understood. I had put on one black shoe and one brown shoe!
Henry: The most embarrassing experience I’ve ever had happened two years ago. After seeing a film, my wife and I had lunch in our favorite restaurant in town. Then we decided to take a walk along the street. The street was very busy and we started holding hands. Suddenly my wife saw a dress in a shop window and stopped. I started looking at some watches in the next window. After a minute or two I reached for my wife’s hand. There was a loud scream, and a woman slapped (拍击) my face. I hadn’t taken my wife’s hand！I'd taken the hand of a stranger!
