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.
Saya ingat ketika saya masih kecil, dan memberikan presentasi di sekolah, saya akan mencatat di selembar kertas, dan saya akan meletakkan buku catatan di belakang kertas jadi orang lain tidak akan bisa melihat kalau kertas itu bergetar.
