This is something I’ll probably take to my grave.
It happened a couple years back. I was a new uni professor. I wasn’t supposed to be teaching on my own that day, but my mentor asked me. I’ve had experiences teaching a class on my own from my previous years as a Teaching/Research Assistant and my mentor knows my old boss (In top tier universities of my country, basically anyone knows anyone from their fields); so my mentor let me.
The class went splendidly. I believe I impressed some students with my style of teaching. When the class is over, everyone left, except for this girl. Let’s just call her Cynth. Cynth, with a pleading voice, asked me whether I would help with her thesis as she’s on her last lifeline and her actual advisor couldn’t be arsed to actually “advise” her. I didn’t think of anything mischiveous at the time, but I was hesitant of overstepping my boundaries as the new guy.
She insisted tho, saying she just needs some directions and she wouldn’t mention me to her actual advisor. I felt bad for her, having been in her place when I was in school, so I said yes.
