I found a free space in winter, and there was a car parked under a snowdrift.
It's winter, knee-deep snow, and a classic example of this: no parking. I pull up to my destination: everything's taken, the yards are packed, someone's already double-parked, and I'm circling, thinking, "If only there was just one window..." And then I see: there's one "free" space! True, instead of a space, there's a snowdrift. But I'm in a jeep, so I'm absolutely confident: "Oh, I'll get there now!"
I turn the wheel and calmly drive forward into the snowdrift. And at that very moment—BAM!—the alarm goes off. And not just anywhere... but right under me. I open the door and freeze: "Is there a car in there?"
A guy with a shovel comes up to me, looks at me as if I'd just parked in his bedroom, and says, "You parked on top of my car!" I answer honestly: "I never even thought there was a car under that snowdrift!" He: "Get out of here."
I quickly get in, back up, and carefully back out of the snowy "parking lot." I get out: "Dude, I'm sorry! Let me help you dig this out." He silently hands me the second shovel: "Thanks." And now the two of us are digging up my most awkward parking spot this winter.
