I been on both sides. I don't think there's an excuse for an adult to act that way. But as a small kid, me and the rest of the refugee kids in the neighborhood, maybe over half a dozen of us would roam the city and raid fruit trees and parks. And get chase off by the owners. I look back at those days now and totally feel bad doing that to any fruit tree owners. As a kid back then we were by no means starving but boy were we hungry all the time. Our parents did not have much money or food. There were things we ate that i look back at now and can't believe no one ever poison themselves. Landscaping trees like the natal plums and the Eugenia trees with its fruits and leaves. I remember them tasting so good as a kid, had them now not so much,lol. Ate sorrel clovers before i know anything about them. Even ate those green spiky maple fruits.
As an adult, I like to share fruits and veggies. I had people stole fruits from me which for the most part I don't mind as long as they don't tresspass onto my property. An example, is a large avocado I have it's so large the limbs crossover and has massive amount of fruits. I don't mind anyone picking any fruits that crosses over my fence and I purposely left it that way. Anything anyone can reach is fine with me. Sometimes, I startle any passers by when they are picking and did not notice I'm right there. I say to them feel free to pick anything u could reach just don't tresspass onto the property. Over the last few years unfortunately I had several adults who jump over onto my property and even one occasion when someone brought a truck and ladder and started loading up on buckets of fruits till my neighbor stop them. That was not the main reason but was one of the reasons I've since cut this 40ft tree or so down to 7ft.
