Smelling ripe peaches or hearing certain Christmas carols can trigger emotional meltdowns that leave you sobbing your eyes bloodshot. But what I didn’t realize before is that triggers like these can also bring memories that warm and comfort you. Sometimes, the thing that plays with your passions smacks you plainly in the gut. Other times, you find yourself shaking your head in disbelief at how the mind can mash your feelings.

Like last Saturday, when a mysterious euphoria set in after a morning hike through lush woods. What on earth could infuse my brain with shear bliss? Was it the wildflowers? The sun? We had new haircuts, the dog and I, and we climbed down a small hill at the end of the trail, and found a shady spot on the quiet country road. There was a pond nearby. Swallows soared overhead. And a cool breeze stroked my bare shoulders. Maybe it was the perfect temperature of the air. Or perhaps it was the sound of my dog lapping water from the cup I held, her whiskers brushing my hand as she gratefully gulped. Could it have simply been my anticipating Chinese leftovers for lunch? I don’t know what it was, but something felt right and vaguely familiar.

Catching up to the friend I’d hiked with, in giddy bewilderment I announced,” I think I feel – happy.”

What triggers your happiness? What triggers your grief?
