OK, I’ll admit it.

I am anxiously awaiting the first joint appearance in four weeks between Democratic presidential nominee Hillary Rodham Clinton and her Republican opponent, Donald J. Trump.

I won’t call it a “debate,” because it isn’t going to be one. They’ll answer questions from a moderator and likely will be unable to question each other.

Why the anxiousness?

I keep hearing and reading things about the way Trump is preparing for this event. He’s relying on ousted Fox News president Roger Ailes, his son Donald Jr., his daughter Ivanka and his new campaign chairman Steve Bannon.

There’s also buzz about how Trump isn’t going to have mock exchanges with stand-ins.

We all saw how he dismantled his GOP primary opponents. He mugged at them, called them names — e.g., Lyin’ Ted and Little Marco.

He faces someone in Clinton, though, who is as unflappable as they come. She’s been through these one-on-one exchanges before, in 2008 against a young U.S. senator named Barack Obama and again this year against U.S. Sen. Bernie Sanders.

Her own preparation likely is going to be as comprehensive as possible. Just how does one prepare for a candidate whose style has been compared to that of a nuclear bomb, or a runaway freight train?

She must expected to the totally unexpected.

There will be two more of these joint appearances with Clinton and Trump, as well as one with the VP picks, U.S. Sen. Tim Kaine and Gov. Mike Pence.

This first one, though, well might be the whole show, the ballgame, the big enchilada.

I’m going to look for two things relating to body language:

* How will they greet each other when they walk onto the stage? Will they exchange warm handshakes, with them grabbing the person’s elbow with the “off hand”? Or will they greet each other with what amounts to a “pinkie handshake” while avoiding eye contact?

* How will it end? Will they still smile at the end of it? Or will Trump’s insults, invective and innuendo be too much for Clinton to take? Or will Trump snub his opponent after she continues to bombard him over his “unfitness to be commander in chief”?

They say the TV audience will be y-u-u-u-g-e.

I believe it. I’ll be one of many millions seeking to take some measure of these individuals.

I’ll have the popcorn ready.
