"I will refrain from getting into moral self criticism about why I don't believe I should be
teaching and how I've become a hypocrite by doing so. For now."
Teaching isn't about having all the answers. We are all teachers to each other, by example
if by nothing else. You can and definitely should be doing it. You have a good eye, you can
give constructive criticism, and most importantly, you know slightly more about the subject
matter than some of the students
Just treat your students honestly and fairly and I'm sure you'll be fine.
