Chronicles of School days - I ... Why blood? Same blood

Mrs.Banu, my XII cse teacher and also my class incharge was teaching some C language crap during december. Me and Ambi were sitting in the last bench with Raj and Muhilan in front of us. Having been warned umpteen times not to talk during class, we were constantly gibbering and gossiping and giggling. And the watchful Mrs.banu ordained us to stand for the rest of the class. Not being able put up with the lecture anymore, I managed to doze off while standing thinking am hidden from her view by Raj.

And to the horror of everyone, I fell aside while sleeping and as a result, ambi was disturbed from his stance clumsily and she noticed it. And due to my special ability to sleep while standing,the whole group got into trouble.She sent us out of the class and dismissed our apologies at the end of the period and also the following day. Finally, on the third day, we went to Commerce class while she was lecturing. She made us wait outside that classroom. Raj and me were talking about Muhilan's goofy act earlier and started laughing meanwhile keeping an eye on the entrance of the class to check whether Mrs.banu is watching us or not. She came out of the class and yelled at us for talking n laughing even while waiting outside her room to apologise.

~~ Uh-hoh, the class had windows ! ~~

She was so furious that she ordered us to meet the principal immediately and more drama was to follow.
We waited outside P's room.And made sure she isn't watching out from tinted windows by calculating the angle from her table. Me and Raj started laughin at ourselves to have messed up things and were cursing fate. Presuming it wont be a big problem convincing our principal, we walked in to find in absolute horror, a huge mirror in the room and a scorning principal.

We could see in the mirror,the place where we had been standing and laughing outside her room moments ago.

And you don't need to be Sherlock Holmes to know what happened next !

Why blood ? Same blood ;)
