Are You Kidding Me?

I've worked at giving my new yard some character and atmosphere. My goal has been to keep the fast-growing trees in top form so that I can look at lots of green.

I have several sitting areas on my modest property. My favorite is a corner with an arbor that is graced by redwood trees. I have two sealed boxes of dog ashes that are the remains of my loyal boy Travis and my child-like Bruno. I have held onto these sealed boxes until I find the perfect place for my dogs to rest. This corner sitting area is ideal--or WAS ideal.

The house next door is finally finished, and they have occupied their property and then some. Here is the view of my favorite back yard space:

Right now I hate my new neighbors and the UGLY net that surrounds their trampoline. They've shoved this monolith to the south side of their house, near their garage so that it's not in their range of sight. Yet, this piece of junk is in eye shot of every main window of my house.

I'm super irritated, disappointed, furious. Do I ask my neighbors to move this? I doubt they care about my feelings. Do considerate people think about what they place in their neighbors' view?
