It's great to find a four-leaf clover or a heart carved in nature. I've blogged about the serendipity of finding hearts where you least expect it (same with a four-leaf clover—less often).
Recently, while on a quick errand to a big box store, I found a parking lot heart configured of flattened and wet boxes. The heart seemed trampled over quite a bit, but once I glanced down, I couldn't walk past it. Not expecting to find anything resembling a heart, especially in a gravelly blacktop, I took a few moments to process what I thought was indeed a heart. Without missing a beat I took my phone out of my pocket and snapped a quick photo. Yep, it was a heart (Okay, a bit of a stretch)!
