Grief is a bad moon a sleeper wave. It's like having an inner combatant a saboteur who at the slightest change in the sunlight or at the first notes of a jingle for a dog food commercial will flick the memory switch bringing tears to your eyes.
In everyone's life at some time our inner fire goes out. It is then burst into flame by an encounter with another human being. We should all be thankful for those people who rekindle the inner spirit.
