Melissa Petro

This really is rather a fun case, that of Melissa Petro and her job as a teacher in the New York school system.

Hooker-turned-teacher Melissa Petro yesterday admitted she knew her sex-for-hire past would land her in detention.

"Didn't you see this coming?" fellow Bronx teacher Ruben Brosbe asked Petro via Facebook after her sordid former sideline was revealed in The Post.

"We talked about it on the first day of training," Brosbe reminded his pal.

"Of course I saw it coming," the feisty Petro, a third-year art teacher at PS 70, wrote back.

Brosbe and Petro declined comment yesterday.

But Petro -- who has been reassigned amid an Education Department probe of her blogging about her exploits as a "former sex worker" -- joked on Facebook about how she hoped a car outside was a teachers-union escort and not "one of the 200 creepy dudes now trying to 'friend' me."

Let's go back to the beginning. Ms. Petro worked, before she trained as a teacher, as both a stripper and an escort. Escort as in the less repulsive name for a hooker. Not something I partake of myself but nor is it something that I think others shouldn't partake of nor supply. And certainly if someone has done such and then decided that they want to change careers well, why not?

Teaching might be a slightly odd choice but then again so what?

Where it all gets really fun is that Petro was blogging this story, even as she was working the three yeasr she had to to gain tenure as a teacher. During this three years her references, character and so on are supposed to be checked out so that it can be seen as just and righteous that she does gain tenure: essentially, that she cannot be fired.

But of course, given that she was writing publicly about tall of this, it turns out that, for yes, she has just been granted tenure, no one was in fact checking references and character.

The egg is on hte school system here, not on Ms. Petro's unconventional former career.
