...Bring it out!" my class teacher said to me. I quietly brought out the white coloured powder from my breast pocket and landed it into his opened left hand.
"what is this?" he asked me. "it's sugar sir" i replied.

"You lie...!" he quickly yelled.
I asked him to give me the powder so i can taste it in his front,
but he refused saying i would lie to him.

He then called out our class prefect, "John, go to the science lab and get me a tiny spatular".
John left quickly and within some seconds, he was back with the spatular in his hand.

My teacher told john to measure a little quantity of the powder and tell him what it tastes like.

John out measured the powder and threw a large amount into his mouth(thinking it was sugar).

"What does it taste like..?" he asked john.
but john couldn't speak, his mouth was just wide open and his eyes started turning red.

"i said, what is the taste..!" he yelled at john.

John struggled to speak but then he quietly stammered. Co......l..os, sir it ...is colos.
