<s>[INST] context: Have you ever had an embarrassing   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   my face. I hadn't taken my wife's hand!I'd taken the hand of a stranger!
