The first I realized she was a spy was back when I was all of 16. I was getting home late one night, about 1 AM. Okay, early one morning. As I was putting the key in the front door I couldn't help but feel that I was being watched. Turning around, I saw no one, but I thought I saw the curtain at the corner window of my grandparents house next door flutter a bit. So I waved at it, tentatively. Grandma pulled the curtains back and returned my wave with a sheepish grin.
So that became our ritual for the rest of the time I lived at my parents' home. If I was late arriving, I would put the key in the lock, step back and wave at the window, and she would invariably appear from behind the drapes and return the greeting.
It seemed however that she was determined to keep an eye on me even after I had married and moved. My wife and I had bought a house down the block on the far side of the street. One day while walking home Grandma asked if I was busy that night. "No," I answered, "Do you need something?"
"Well, I need that tree trimmed," she replied, pointing at the one in her front yard next to the porch.
"I'll be here at six," I told her, moving along.
So I returned then with my saw, and set to work at her direction. After about an hour I asked, "So what's wrong, Gram? Why do you need this tree trimmed?"
"I need to see all the way down to your house," she explained matter-of-factly.
From that night on, when getting home late at my own abode, I would turn towards her house from my front steps and wave. I wonder if she ever noticed?
