Just a few examples of my own:
Insecure bridge player: The queen of spades was a stupid play. What's wrong with you?
Excellent bridge player: The queen of spades would have been a great play against a 4/2 split. But since you had a 3/3 split, what do you think would have happened if you had played the ace instead?
Insecure public speaker: You look like an idiot playing with your hands like that.
Excellent public speaker: You talked about a lot of cool things. I bet I would have been even more interested if I wasn't distracted so much by your hand gestures.
Insecure parent: If you can't keep that baby quiet, you should just stay at home!
Excellent parent: Here's something that has really worked well for me when my kids cried in public...
Insecure programmer: How lame. I can't believe you <insert almost anything you could have done>.
Excellent programmer: I see that works. I have found a few ways to make it work even better. Let me know what you think.
