Do you play jokes on April Fool's Day?

No, I don't think it's a tradition in Hong Kong. I never treat it as a special day. I'm a good student and I don't like to play jokes on others. But once a close friend - an 18-year-old student - played an April Fool's joke on me. She told me that she was pregnant and did not know what to do. I tried my best to comfort her. I worried for a month before I released that it was just a joke.

No, April Fool's Day is not popular in Hong Kong.

I seldom play jokes on my friends. Two or three months ago, I was playing mahjong with some friends. Most of us wanted to stop after some time but one person insisted that we continue. So we hid a mahjong tile which prevented us from continuing the game. Before we left, we took out the tile and told her about the trick.

Yes, I have played jokes on my friends on April Fool's Day. One time I called a friend in disguise and said that I wanted to date him. I told him that I had been following him for some time and knew which school he went to and where he lived. He was very scared till I told him who I was.

Yes, I think April Fool's is a fun day. I once called my male friends on April 1 and said I had something important to tell them. I said there were three words I wanted to say, and one of them was 'you'. The boys were hesitant at first because they thought I was going to tell them 'I love you', but I actually told them: 'You were fooled!'

Yes, I once played a big joke on a friend who was studying overseas. I called him and said that his mum was very ill and her greatest wish was to see him get married. My friend was very nervous. He called his girlfriend immediately and proposed to her but was rejected. When I told him the truth later, he was very angry and told me not to play any more tricks on him.
