Dr Jekyll or Mr Hyde?!

 There comes a time once or twice if our luck is as bad as our fate, in a week when the dreaded timetable outside the Physiology lab brings us closer to our doom and the rush of your friend's voices finally tells you that your eyesight is perfect, ensuring the presence of the dreaded P.S in your class tomorrow! You must be wondering who this P.S is. No, it does not stand for "Psychotic Sir". His name instead of Sir Perwaiz Sandhela (or is it Sandhila?) is accentuated as P.S for I don't know what reason as in to induce fear in our heart's!
So, when this day arrives all the kids are seen huddled up in the middle of every bench, no one is very eager to sit at the corners to risk getting their face slapped or ears pinched.Physiology books are open in the Anatomy class and the students pretend to listen to the origin of Deltoid while memorizing the functions of cell membrane. At last the dreaded bell rings and a scuffle ensues at the front of the class, all the boys clambering to sit in the middle and the corner seat near the wall or risk getting their ego busted. The ones sitting near the walls are very much hidden with their shoulders hunched up looking like a worn out Hunch Back of Notre Dam. Talking ceases abruptly and whispers die down as the P.S saunters into the class, slithering like a snake and every one who is watching him getting glazed eyes and very eager to see who gets the first knock on the head. The P.S spends most of his time teaching while sitting on the chair and now as he sits down due to the pure relief of the students, sighs are echoed down the benches. Today, he seems to be in a good mood but you can never tell, don't get your hopes high. All through the lecture, students sit in fear. Suddenly he stands up, bequeathing the ground beneath him and demanding an answer from the victim while boxing his ears. In about 10 minutes or so about 5 boys have had their faces slapped and 2 girls have been called the 'off-spring of an owl'( it does not sound insulting but try saying it in Urdu). Like a bull, he ravages the whole class, noticing the flickering red cloth every where and charging upon the wretched prey. Finally after taking the attendance (you have to raise your arm as swiftly as Flash or watch the murderous look on his face) he leaves the class sauntering in his gait and perhaps chuckling to himself, "The fools! One swipe at the head and I've got 'em eating outta my hand!" While, us poor larks have to wait one whole week to see this showdown drama again.....!!
