Was going through the new posts and love this quote!
What I take from it is that even if you have fine, strong, resolute morals and strength, if you hang out in the wrong places, with the wrong people, the wrong influences etc, you too will fall and be affected.
Don't believe yourself infallible to fall or be affected. It's like hanging out in a bar all day expecting never to drink!

And these days we get people more worried that we call them by the correct pronoun.......going backwards?
