I asked A why didn't he practice this week. He was always a star pupil.
"I lost my memory during the week. It took everything, I forgot how to play the violin."
" oh? Tell me how you lost it."
"Okay, so... when I was sleeping, a big man came into my room and he put his hands on my head and then in the morning when I woke up I forgot everything. I forgot the spelling words I memorised and I forgot how to play the violin."
" oh? so...how do you know how to play it now?"
" I have a back up memory box, I keep all my memories inside so I can just open it and then breathe in the memories and I'd have it in my head again. So since I have my memory back now, I'll practice my violin this week."
