I've never understood the whole thing there. It's not really any of ours' business. Frankly, it isn't a big deal, either. So somebody had a relationship...is that so abnormal? No.
You didn't really expose anything so much as you did the digital equivalent of yelling "Hey, the guy standing next to me has a wristwatch!" in the lobby of a hotel. That isn't really a big deal. Likewise, neither was what you were arguing about.
On a more significant note, has anybody tried those ketchup flavored doritos? I saw a pack on sale at Wal-Mart and I'm wondering what they're like.
