I was working alone in my orchard, which I'd first cleared the land of thornbush before planting fruit trees. Hard but rewarding work. One evening I was approached by a woman in her late 40s. She'd seen me working there several times, and she wondered if her son could come and volunteer to help in the orchard. It was as part of a public service award scheme. After some questions I decided it was a possibility and agreed to a trial period. Two days later the lady arrived with her son in tow. He was a good looking young man, slim with a great smile. My gaydar was firing. She hung around during the first session which I devoted to safety training. During subsequent sessions he was unaccompanied and at that time of the year with the surrounding woodland we'd be undisturbed. I discovered that in two weeks he'd turn 16 (the legal age of consent). He was wearing shorts, boots and a tee shirt. I resisted temptation that evening and for the next four years, though I've little doubt he was interested in experimenting.
Since then after leaving school, he's been to university, and has started his career in media. We remain great friends, and he has a boyfriend.
The point I want to make is that, I gained much more by watching, and helping, him develop into an adult. If the relationship had turned sexual I doubt it would have lasted long.
