What is absent-mindedness?
Once my class-teacher asked me to take the attendance of the class and mark it in the register.
Immensely proud of the fact that the teacher chose me for such an important(Yeah! Important!) work out of a class of 40 students, I held a RED pen in one hand and the register in another, stood facing the class condescendingly and blurted, ” Who all are absent? Raise your hands.”
Oblivious as I was, it took me a while to realize what wrong had I said that made the class go hysterical!
