Neighbor Relations

So, when we bought our new house, we had heard about a few neighbors who were nosy. Maybe they were just trying to be helpful, but we'll never know. Apparently, this particular piece of property has been a campground to some folks and a dog poop park for others. We didn't know we would be changing peoples routines by building a house here. Pretty quickly, we put up a Fiddler Island, Private sign. Just in case. Our driveway is sort of hidden, but we wanted wanderers to know that we were living there now.

One day I was driving out the driveway and our neighbor was standing with her dog. There's a spot of land, right before the little bridge, that is perfect for dog poop. So, I stopped and talked to her. She's my age and expecting her 2nd. Very friendly. She asked if we were living here now and I responded very politely, Yes. She hasn't come back with her dog since.

Another day, I looked out the window and saw another lady with her little dog in the same area. We had cars in the driveway, so it's not as though the house looked vacant. Anyways, I wanted to run out and talk to her, but the dog finished her business and they went along.

So, i got to thinking about things to say, should I see it happen again.
1. Hi! I think it's great that we're all allowed to let our dogs poop in each other's yard. Which house is yours?
2. Hi! Next time, please bring a bag to pick up the poop. (This is ironic because if they wanted to pick up their mess, they would do it in their own yard).

But after I discussed with Alex, he didn't think it would be good for neighbor relations.

But this really got to me, I was walking out of the house with the boys and there on our bridge was a couple with 2 large dogs. They were just walking along and probably gonna let their big ol' dogs go in our yard too. But they saw me, stopped, pretended to point to something and turned around. I mean, who just goes for walks on other peoples properties????

Anyways, I think the Private sign is working because I haven't seen any visitors lately.
