Speech

A member of Congress is visiting our company tomorrow and I'm giving a presentation.

After introducing myself, I say, "On behalf of the xxxxxx department, I would like to welcome you all to xxxxxx".

Do you think I should single out the Congress member in my welcoming statement since they're going to be our guest of honor? If so, how should I word it?

Leave out the "you all", "you" will suffice - otherwise you might sound like a Southern hick.

<<Leave out the "you all", "you" will suffice - otherwise you might sound like a Southern hick. >>

Wrong.
The note of "you all" above is not indicative in any way of being Southern. That would be "y'all".

Here, "you all" is the same as "all of you".

You can leave it in. It sounds fine.

Find out the Congressman's precise title and of course single him out as a guest of honour. I would say, do so with relish and unapologetically.

"They're going" you say ?- Why are you concealing the sex of the Congressman from us ?
