@Valour 22 May 2021 more from that month

I drew this a long time ago in my note. Normally the lecturer do give us Pdfs of drawings to print and work with, but I noticed that after each semester the drawing do get lost and we are left with just our calculation notes, I decided to draw it in my note so I can forever make reference to it when reading. My lecturer called be a "Jobless fellow" and the whole class laughed. The first call I received this morning was from him ,he asked me to please give him my notes that he needs it to teach the 200L students especially the drawing references I made. He made jest of me in public but he is now complimenting me in private.
