^People are often confused by the "One Minute Manager" of
  dealing with bad news. It known to work on employees, adults,
  customers, kids too. It's simple, but bewildering if you see it
  and don't realize it's happening. This is how it works: When you
  have bad news to present to someone, you start off with a
  Compliment ("Great job on such-and-so!") then the Complaint
  ("But you really shouldn't hav...e done this because..."), Then
  end with a Compliment ("But it really was a great job on
  such-and-so"). I use it ALL the time since the early 90's and it
  always works on the person I'm dealing with. It's a way of
  talking that makes you appear to be Mr./Mrs. Positive -
  everybody ends up with a smile - yet the bad news comes through
  just fine with just the quickest frown which goes right back to
  a smile. Example: Kid breaks a window. "Wow, that was one heck
  of a fastball!" "But you know you have to apologize to Mr. Smith
  and we'll take the cost out of your allowance" (wait for
  agreement) "But man, we'll have to get you in training camp this
  summer to work on it - just stay away from those windows - haha"
  pat on the back. Money comes out of allowance, kid apologises as
  required and no hard feelings from anyone. It comes so
  automatically to me now that I don't even realize I'm doing when
  I'm doing it :-) But I highly recommend it - it feels strange at
  first (it did to me back in the early 90's) but then it comes
  naturally.^
