I would like to talk to the parents if only the kids were doing it.In my case the mom did that too.walking the dog through my property. And just the other day like I mentioned in my previous post all were waking together up until my property and then the older kids took the short cut and mom continued to walk on the curb with her stroller. She definitely saw and have not tried to stop her kids obviously. If I saw my kids walking on someone's lawn,I would surely say.....hey,kids come walk with me on the curb.But she kind of approved it.So what is the point in talking with the mom? One time last year,I was just 10 feet away,when the mom and kids and dog were crossing.They didn't notice me ,I was behind a bush.I have seen them a couple of times by then.So I thought let me make myself visible to them and convey the message that I have noticed them.I walked and stood in the middle of my lawn and was in their peripheral vision.They could see me from the corner of their eyes.All of them put on poker faces and walked through to my surprise. Now a days they actually turn their faces towards the house,specially the mom and dad,with a smug,arrogant and angry expressions as if I have wronged them by standing in the middle of my lawn staring at them.
