How do you feel when you are fooled by others？ No doubt， feel bad． There is nothing worse than falling for a joke and being a fool except one day． Yes， that's April Fool's Day． Nobody will be angry to be an" April Fool"．（1） 　　

The headmaster at my school decided to play an April Fools' joke on the students when I was in high school． On March 31， she announced that our school would hold a "Dress to Impress" day．（2） 　　

Girls were told to wear formal dresses and smart jackets， while a suit jacket and tie for each boy would be best． The teachers， we were told， would do the same．

On April Fool's Day， many of us students came to school dressed in our best clothes．（3） 　　In the morning， all of us got together on the playground， waiting for the headmaster． She would speak to the students．（4） 　　Instead， she wore jeans， running shoes and a T﹣shirt． The teachers also got dressed casually like her．

"April Fools!" she said， with a big smile on her face． "We just wanted to remind you that teachers have a sense of humor， too!"

Surely， all the teachers weren't April Fools．（5） 　　

A． Our hair was tidy and all our shoes were well cleaned． B． People say something nice to others on that day． C． All us students spent the rest of the day feeling very foolish indeed． D． This meant that the better you dressed at school， the higher your marks would be． E． But everyone knows to be careful on the first day of April． F． To our surprise， she wasn't dressed up at all． G． My parents laugh at each other's jokes．
