These days would never come back.

.Eeeeeeeh, in the hematology lecture, when the professor was preparing her slide show, some of us wanted the slides to occupy the full screen, but our professor was confused by us keeping telling her all of all at the same time go up, no no left, nooooo right, oh you missed it, and that kind of stuff, at last one of us who were in the front row went down to her and pressed f5 and so many of us clapped greetingly, the professor smiled joyously and we laughed, it is one of the candid and naive moments of spontaneous unexpected events that inspire happiness, we were happy for sometime and after we enter the maze of life it isn't likely to have something like that again, it was just a note for history
