I have an a-ha moment every day except in summer when I hibernate from the heat, the snakes and smoky air. During the rest of the year, I walk in the nearby desert hills with my dogs where they case the ever elusive jackalopes.
My most memorable moment was when I was working on a character in my novel. Afflicted by a long forgotten trauma, she is incapable of movement for one minute twice a day - at 10:10 and 1:50. The first time I played with this IRL was when I came in the door and saw that it was 1:50.
"I stand in the middle of my living room and stare out the sliding door. A wren is on the power lines, scooting back and forth, head bobbing to his own sweet song - just doing his birdie thing. On the commercial lot behind my house, a construction worker is making exactly the same movements - I can only see his head and chest, the fence obstructing the rest of his body. He's whistling as he picks up litter from the ground. During that moment in time, nature and man are in perfect unison. Each of them unaware of the other."
