i took a philosophy class last semester and i really enjoyed the class and my prof, i participated in discussions and talked to him after class a lot, and i waved and we said hello when i saw him in the hall. he sent me an email a few weeks ago asking how my classes are going, and we’ve seen each other in the halls since. i want to send him a youtube video with some interesting ethical dilemmas, but i’m not sure if that’s strange. if you were a prof and a former student emailed you out of the blue, what would you think?
