Yes, of course carbonproduct. I am one of those people who won't hesitate to say something to keep another person from feeling embarrassed. Although, I will throw in a caveat. If it's a man who is a stranger to me and his fly is down, I don't usually say anything. Er, not because I'm hoping to see anything but because it's just embarrassing to both him and me. Why the heck was I looking there in the first place? Ack! I don't know! Automatic reflex? lol.
As I'm writing this I have to admit something. Don't tell anyone but, if I saw someone I really can't stand with food stuck in their teeth, something on their face, toilet paper on a shoe, his fly down,.... I wouldn't say anything.
HAHAHAHa When Im eyeballing someone inappropriately and notice an unzipped drawer or boob peeking out, I just stare. I find myself in luck, but thats just me. ;+
