Lectures

In high school I learnt a funny trick to avoid literally falling a sleep in a boring lecture. It consist of raising your hand and coming up with a question related to the topic title. Piece of cake with whiteboards. Not so easy in a  series of  powerpoint lectures. Let's say I made the whole class confused today. I am pretty sure the tutor thought me asking him was part of day dreaming. Hey even maybe a stroke. He asked me to read the next slide, maybe to assess my mental state.
I have no idea what I said. But from my classmates reaction, it sounded genius.

Good news, I stayed awake for the rest of day.
