Yesterday we only had 3 of us there (including me). My speech would be given to an audience of 2.
I had a speech – and as I walked up I came up with an idea. Let's acknowledge the obvious:
“Mr. Toastmaster, Fellow Toastmaster.”
Background if you're not a Toastmaster: People frequently start their speeches with "Mr. Toastmaster, Fellow Toastmasters..." I'm not a fan of this approach because it no longer grabs attention. But the singular "Toastmaster" did.
