Although I never quite made it to the Bradley Manning level, I’ve been a leaker most of my life for all the wrong reasons. It’s not that I believe in truth or justice or transparency – I just want a little attention. That’s why, one night at the dinner table when I was eleven years old, I cagily revealed to my older brother that he was going to find a Matchbox Car in his birthday haul the next day, but I was not going to tell him which one in the set he was going to receive.

This, I thought, would give me supreme power over him.

Naturally, my mother was outraged that I had betrayed her confidence. I was sent to my room immediately, forced to skip desert.

At the time, I didn’t quite understand the outrage. We each had accumulated a ton of the tiny metal cars, so getting another one was not that big a deal. Which model though? That was the key (as any collector would understand), and I was keeping that significant detail to myself. He would be tormented to have to spend the night knowing there was a new vehicle in his stable and wondering which one it was, praying and hoping it would be the Jaguar XKE when I knew full well it was the Ford Galaxie Police Cruiser. Not only would he spend the night in agony, his morning would be poisoned by disappointment.

No actual harm done. What’s the problem?

But in my mother’s mind, I had spoiled her surprise, and I played Edward Snowden to her Lindsey Graham. If she’d had access to the worst gateway lounge in a Russian airport, she would have marooned me there forever, or at least until I apologized to everyone in our family minus the dog.

Which was odd, considering that a few months later the dog was the one who would eventually wind up with that Matchbox Car firmly in his mouth – an unsatisfying substitute for a bone on a dreary, nothing-happening day.

When have you spilled a big secret?
