"No Regrets"

Am I the only that gets extremely annoyed whenever anyone says "I have no regrets" or "If I could do it all over again, I wouldn't change anything" or anything alone those lines?
Let me make this clear: I have a lot of regrets, and if I could do it all over again, I would change many things. That's not because I'm living in the past, it's because I'm living on Earth.
Aside from the blatant dishonesty inherent to claiming to have no regrets, the other thing that bothers me about it is that a person with no regrets is probably a complete asshole. For instance:
Joe: "You know Bob, I really didn't appreciate it when you fucked my girlfriend."
Bob: "Meh, I have no regrets."
Obviously most of us haven't fucked someone else's girlfriend, but we've all done things that we should regret, not just for our sake, but for everyone else's.
Next time someone tells me they have no regrets, I want to punch them in the face and then ask, "Oh really, do you regret saying that?"
