Last Thursday, I was invited to the 10-year-old birthday celebration at school

During the party , children sang songs and danced and recited poems .

There were also lots of parents joining the party .

Everybody enjoyed the whole party except for the unfortunate matter taking place later.

After the headmaster had announced the show had been over , most of us exclaimed

And some children could not help breaking the balloons which were serving as the decoration around the hall

My father got angry .

 And I was not  allowed  to join the crowd at that moment ,

He must have been thinking that a polite child should not behave himself like that .

Meanwhile ,I had to leave with him.

 

Questions

 What kind of party did the writer join?

 Did his father go with him?

 What did some children break after the show had been over?

 Why did his father get angry afterwards?
