"Hi Nick, this post struck a chord when i read it! I've had similar experiences over the years, normally with a frustrated person who wants to make their own speech and just relishes the opportunity to stomp all over my material! Anyway...it happened again last night! For once I was brilliant...got 'em ,fired them up,kept it tight...and as you know, if as a speaker you feel it was good, it was good. Anyway, Mr Grumpy is asked to give the vote of thanks...and clearly despite the audiences' great response ,it had all passed him by..." You shared lots of ideas we've heard before....interested that you've spoken in Rio,I presume you can speak Portuguese...I presume your message was for us to take personal responsibility, well, I'd like to think you were speaking to the converted" All I could think was that either I had said something to get his back up , or there was something going on in his life that was causing him pain and it eased the pain to have a dig at me. My big disappointment was for the audience who, to my mind, were somewhat deflated by these final remarks. Anyway, there is often "one" in the audience...and its just bad news if they get asked to give the vote of thanks. I write my own introduction, and insist its used...I have often thought about doing my own vote of thanks! Keep up the great work and don't let them get you down!"
