Compliments are most trustworthy when they are received through a third party.
I thought you would like to know that, and I am pleased to pass it on to you. A third compliment on your performance was solicited. A couple of days after returning from our Convention, I received a call from a friend who wanted to talk about some of the interesting things that went on there. It was then that I asked how he thought you did conducting the remainder of the meeting after my opening remarks.
