Unlucky Tidings

The Guntur Gorilla, also the Engineering Drawing teacher of the Prosaic Hallucinator, was a pain in the neck and the bottom. His eye spotted some minor mistake or the other in every drawing sheet upon submission and had worst analogies to point them out. The Bespectacled Smart Alec was the worst-hit, being sent back to his desk more or less a dozen times.
The Prosaic Hallucinator was observing all the mistakes others were accused of, and corrected them in his sheet. As a result, he produced a flawless piece and was impressed so much that he considered framing it in his room.
Even the teacher beamed at it when it was submitted and looked like he was now having framing ideas.
'Gentleman', he said.
'Sir?'
'You are the first person to submit without any mistake.'
The Prosaic Hallucinator badly desired to bow at his teacher, grab his hand and plant a kiss. Before he could say 'You bet, sir', the Guntur Gorilla continued:
'But..'
'Sir?'
'This is not a drawing sheet. This is a xerox parer! You have to re-draw the whole thing on a drawing sheet and submit on Friday.'
The Prosaic Hallucinator's heart skipped two or three beats.
'Re-draw, sir?'
'Yes.'
'The whole thing, sir?'
'Yes, man.'
'Can't I start using drawing sheets the next assignment onwards, sir?'
'You have to re-draw, man. Otherwise I won't evaluate it.'
The spring in the Prosaic Hallucinator's walk after the Change of Branch results was replaced by drooping shoulders.
The gods are jealous, was his recurring thought.

His conclusion at first was that the man at Gurunath had given him the wrong sheets. But then he remembered that he had actually used one of the two sheets rolled up inside the chart the Headstrong Room-Partner had lent him. Arriving at the room, the Headstrong Room-Partner denied that those sheets were his. He showed the rest of his pile -- they were bonafide drawing sheets.
At the mess, the Prosaic Hallucinator and the Physics Enthusiast met. The former learnt that even the latter did not use "proper drawing sheets" and was asked to re-draw. They hugged. Nothing sets up friendship like a common enemy. The story was spread as they ate.
Lunch taken, the Prosaic Hallucinator started to head home, and saw the Intolerant Amnesiac up the road. The Prosaic Hallucinator briefed him on his unlucky tidings.
'You butter-boy!', ejaculated the Amnesiac, 'Do you remember the other day you and I sat together with our charts in Math class? I inserted into my chart two sheets I had borrowed, and our charts got switched.'
'Whom did you borrow the sheets from?'
'The Physics Enthusiast.'
