Amid all the gala premieres and Earth-shattering Paris Hilton controversies gripping Toronto as its film festival gets underway, only one subplot in particular has managed to coax psychoanalysts and romantic advice gurus alike out of their plush-lined caves. And to be honest, we can't believe we didn't think of it sooner: What should exes Brad Pitt and Jennifer Aniston — both in town with new films — do should they bump into each other on some congested red carpet, or while picking up one of those delicious sausages on Bloor Street? That's heartburn enough — but it doesn't have to be crippling, argues today's Globe and Mail:

[I]f Mr. Pitt does show up at an event Ms. Aniston is attending, it behooves him to initiate an interaction.

"The ball's more in his court to be gracious to her and to be a gentleman," says Dr. Fulbright, adding that acceptable patter could include saying how nice it is to see her and congratulating her on her movie. For her part, Ms. Aniston should avoid being too animated. "Most of us try to be extra-clever and extra-charming," Ms. Vogels says. "It's so transparent. Everyone can tell you're overcompensating." By the same token, a killer dress and a hot date is great but only if you're not using them as bait or continually checking to see whether you're being noticed. Finally, it benefits both parties to keep it brief, have an exit strategy — such as meeting up with a friend — and avoid too many drinks, Ms. Vogels says.

Still, we don't see this scenario playing out very well for either party, with Aniston's awkward inquiries inevitably leading to the subject of new twins Knox and Vivienne, followed by Pitt's response, "Couldn't be better — here, I got pictures," and his back-pocket extraction of a dog-eared copy of People's Aug. 4 issue. "Here, you can have it. Show it to... What's his name? Where are you going?" Oh, but for small miracles.
