Neighbor problems.

[Velisra]

There is some outdoor furnishing that you can even place such as one side of them is on your neighboor's terrain.
For example the Living Arch:

You can place it so one end is on your lawn, and the other end on your neighboor's lawn. Allowing for a friendly bridge, at least if it is consensual

This is great (if consensual, obviously!). Makes me wish that my house was closer to either my FC house or my aunt's house. Mine is in the Beds, the FC in Mist and my aunt's is in the Goblet, so no chance of a lovely arch to link our plots!

OP, I totally get you. I realize it's "public space" but it's still MY YARD dangit.

I've had a little lala jumping about in my yard at times. I just thought it was weird and ignored him. Maybe just ignore the neighbors and eventually, when they don't get your attention, they will not come back?

ETA: Thinking more on this:

I realize this is a game with pixels and all, but still. Would you be okay with people doing this in your yard IRL? Nope.

The other day, I looked out my back window to see some woman wandering through my back yard. I had no idea who she was. Our yard is not fenced (many in our neighborhood are not; I like it that the deer--and occasionally my neighbor's horse!--come wandering through every now and again), but still. Is it okay for some unknown person to just wander around on private property? NO!

I did question this woman in my yard, but I wish I'd been gutsy enough to say what I really should have said (I'm very non-confrontational and you never know with people these days...). I should have said "Next time you're looking for a dog, better come to the front door and ASK first, or I might shoot first and ask questions later."

So yeah, it's a game, but again, it's still MY YARD.
