Total Defence Celebration.

There was a Total Defence Day celebration in school.Classes were as per normal when suddenly a loud siren was heard ll over the school.Mrs Menon gave an announcement that there was an explosion at science lab at level 2.
And most importantly, Mrs Menon said that especially the second floor students.I got so paniced at that moment.Mr Koh immediately led us to the school field.Some irresponsible students from other class,were walking slowly.When she saw this,she shouted at them hushly.They got so shocked and ran towards the field.Later Mrs Mnon briefed us about the need of the emergency evacuation.Then I underdstood that we should take this kind of exercises seriously.
Later we proceeded to our classes.Our lessons resumed.Mr Koh gave out each of us 5pieces of post-its to write about our of thoughts for total defence.It was recess.And it was food rationing.So canteen was closed.Everybody was each given a bun and a bottle of water.Then our teacher explained how fortunate we were.And he said that we are to atleast get a piece of clean water and a bread.
After that we had a trail .Our job was to paste our reflections and was to learn more about total defence.
