And I learned what truly endures in this uncertain existence: "It is a glimpse of play out an open window, a knowing smile at bedtime, a sleepy head resting on a shoulder, a sigh of contentment, a cheerful wave hello. It is a moment of warmth, a secret shared breathlessly, a casual glance that says nothing in particular, but says all. It is a quick impression, a flash of pride, a stolen hug, a silent tear. It is a thousand, thousand such moments, each of them a heartbeat, all of them a lifetime. It is what we were to each other. It is what we are to each other. It is all that happened. It is all that didn't."
