A couple of ethical questions for you:
You are riding with your buddy and you see something similar to this:

Do you tell him his shorts are wearing out?
Now the hard one. You are a guy and the person with thin shorts is a woman. Do you tell her? And if so, how?!
Yes, this actually happened to me this year. I’m not saying what I did, but I’m still alive, so you may be able to guess.
