I'm kind of in a quandry about this, the other day I was in the post office and the guy in front of me had a large bad looking growth on his neck. I figure there was no way he couldn't not know about it but it was on the back of his neck, but then I started to wonder if I should say something to him about getting it looked at. I ended up deciding to mind my own business and not say anything. But anyone else ever encountered this? Did you say anything? A nurse friend of mine told me she saw a lady sitting in front of her in a movie theater with a mole that looked like skin cancer and just leaned over and said "I'm a nurse you need to get your mole checked" The woman spit out her popcorn and changed her seat. I mean it seems right to say something but it also seems wrong, like invading privacy.
