And I can assure you that your voice was the most attentively
followed factor on lots of those 'close encounters of the nervous
kind' too...not just the words either but the tone of voice too.

You no doubt were trained to deliver those words in a monotone
but when several pairs of ears are hanging onto every clue
available then pretty damned slight variations are well noted.

Been there and done that at least hundreds of times...too many of
which were where God supplied the 'blind flying hood'.

Thanks for all the successful outcomes of your (and your
cohorts') efforts sir.
