When people pretend to be vulnerable, especially when they take on a childish attitude, to avoid acknowledging a mistake!
Acknowledging a mistake is the best and sanest way to defuse irritation or anger when you've done something you're gonna have to own up to some day, so just get it over with and save everyone the grief. Of course, there are limits--like if you drone strike a wedding party, "oops, my bad," just doesn't quite cut it, so you come up with some BS like 'collateral damage." Right! I'll collateral damage your ass, mofo! (or do they call that jihad?) Be careful with those friggin' drones!
What pisses me off today is my dog! Who always wait till there’s a hot guy in front of me to poo!
