It took a small freight truck to really smash the cake. A Jeep had clipped it, most of the cars had managed to get around it without touching it. Not being a jerk, he'd put the modest three-layer construct on the edge of the lane, and sat watching from the hillock just beyond the shoulder on the other side of the country highway.
But he wanted to see it smashed, and now he had. Smashing it himself would seem like cheating, in at least two senses...he hadn't been responsible, not directly, for what happened to her, so why should he take it out completely on his own on the cake. And, of course, actually attacking the cake himself would also seem like an attack on the wedding, an attack on their union, on her. If he had any hostility toward her, it was only the resentment that she was gone...and he couldn't begin to resent her very much, so much as to want to, well, destroy the world. Better, instead, to passively destroy the overpriced cake that, of course, couldn't be returned nor cheerfully disposed with (hey, want some cake that she would've rubbed my face in?).
Like most wedding cake, it wasn't even all that good. It had been pretty. He'd taken a bite of the top layer before solemnly setting it down just inside the white line on Rt. 43 West.
You never really know which airplanes will crash. Nor when. Nor who will be aboard. Nor why you weren't on the flight with her, except for the petty bit of business that would've put him on the redeye the next morning...if it hadn't been moot by 7pm that evening.
Or so he reflected, as he watched a sedan splatter some of the remains of the cake onto the shoulder. He decided he'd watch this for another hour...it'd be dark by then. He had no idea what he'd do then, but it didn't matter much, and probably wouldn't for a while.
