How to say you're sorry with the proper intonation!

I found a nice collection of postcards (see the caption below the card). One of them lends itself to a short exercise in English intonation. It depicts 11 situations in which regret is expressed (or not). Try to put yourself into the person's shoes. How would you say "Sorry"?

If the text is too small for you to read, go to the webpages of the authors and click postcard no. 26. My apologies to the copyright-holders for adding numbers to their drawings.
