When my boss replies with "sounds good" I start looking for my next job. I totally agree with "let me know". These simple 2 or 3-word phrases can mean very different things in different English-speaking subcultures. Here's what UrbanDictionary says about a variant: > LET ME KNOW HOW THAT WORKS OUT FOR YOU the easiest way to end an argument when your opponent relays their intentions to do something that you do not agree with. http://www.urbandictionary.com/define.php?term=let%20me%20know%20how%20that%20works%20out%20for%20you http://www.urbandictionary.com/define.php?term=let%20me%20kn... or how about "good luck" ? http://www.urbandictionary.com/define.php?term=good+luck http://www.urbandictionary.com/define.php?term=good+luck GOOD LUCK a phrase used to wish someone well in an endeavor sometimes a pointless phrase if the task at hand does not even remotely involve or require luck. Ex. good luck washing those dishes. i hope the knives don't fall on your foot and slice your toes off! This is interesting from a theoretical perspective as well. In linguistics, all languages have what are known was "particles" - words that are so frequent it is difficult to ascribe any meaning to them, and yet they shade our language.
