When I started teaching at the university, I had a lot of acquaintances since I was a student there, so a good amount of the professors were my teachers.
I had been teaching for a week or two at the time, but I still haven’t got my key to the classroom, so I had to ask another professor passing by to open the classroom for me. One day LACS was passing by and I asked, he of course opened the classroom for me and went to his cubicle, he came back and told me he heard I was teaching but hasn’t seen me yet, now that he saw with his eyes he wanted to the welcome me to the guild, so he gave an eraser and a marker.
I already had a marker(exactly the same as the one he gave me) and a similar eraser and what he gave was just another marker and eraser he had but it is the only welcome gift I received at the time on my first job and it came from the best professor the faculty had who was also my tutor…to the day I still have both marker and eraser, stored on a ziploc bag as a fond memory of my early years and one of the only 2 things I have from lacs.
