I remember when I was a kid, giving presentations in school, I would have my notes on a piece of paper, and I would put a notebook behind the paper so that people wouldn't be able to see the paper quivering.
Je me souviens quand j'étais enfant, lorsque je faisais des exposés, j'avais des notes sur un bout de papier et je posais un cahier en-dessous pour ne pas que les gens remarquent le papier qui tremble.
