Varia points me to an article in the New York Times, in which a tale is told of a woman breaking up with her man via Powerpoint.

“Let’s end things now, tonight, while we’re a little buzzed and in good moods.”
He paled, straightened, slumped. “Why?”

I reached into my bag and, nodding somberly, pulled out my laptop, resting it on the bar in front of us. [...]

When the presentation ended (with a bulleted list enumerating the many good times we had had, to end on an up note), I snapped my laptop shut and turned to face him. “Well?”

He ordered another drink, and we sat in complete silence for as long as it took him to finish it. I slipped my laptop back into my bag, paid the tab and hailed myself a cab.
