This happened to me during our induction process when I first joined IBM. We were all graduate hires, fresh out of college, not yet recovered from the college hangover. 🙂
So, there was a female instructor (probably for Oracle PL/SQL) who was teaching us more on the values of life than the subject matter at hand. Many were dozing off due to all the ‘gyan’ (remember the college hangover) and weren’t really paying attention to her anymore.
Suddenly, she had a moment of divine realization and asked one of the girls in the front row to sing. Maybe it was her way of breaking the monotony and waking the sleepy heads up. The girl sang well, if I remember correctly. We clapped. Suddenly, the lady points at me in the distant corner and says ‘you look like you have a nice voice! Can you sing for us?’
