Blessings from the Heavens
The experience of being hit with bird droppings on their way to and from anywhere in the campus is so common for IIScians that they often don't even flinch on that happening. Often, the more immaculately dressed up people the campus would take out their handkerchief and coolly wipe away the stain and are promptly on their way; while more Laapataa-like people wouldn't bother to do even that much, and would be seen wearing the same shirt days later with a dried up stain.
Folklores abound about these blessings from the heavens. It's said that you are in for some good academic times if it happens with you. If you are hit right on your head, you have got a jackpot!
Everything apart, somehow being hit by crow shit is implicitly considered an inherent part of the IISc experience. Not because it smells. But because it reminds us in another way, that we are a fortunate lot to be living in such a lush green campus.
