AIO for asking my neighbor to stop holding her yoga classes in my backyard?

So, a few months ago, my next-door neighbor, Karen, started teaching yoga classes in her backyard. No big deal, right? Except, her “backyard” has slowly started to spill over into my backyard. At first, it was just a mat or two near the fence, but now her whole group of yogis basically takes over half of my lawn every Saturday morning.

One day, I look out the window, and they’ve set up an entire speaker system blasting calming nature sounds and “healing frequencies,” all while I’m trying to enjoy my coffee in peace. I politely asked her if she could keep her classes to her own side of the fence, and she just laughed, saying, “Oh, it’s all one big green space anyway!”

The kicker? Last weekend, they brought out incense, and suddenly my backyard smelled like a meditation retreat while I’m trying to grill burgers. I asked her, again, to maybe shift the class back into her own yard. She told me I was being too territorial about “shared nature” and should appreciate the community vibe.

So, am I overreacting for wanting to reclaim my own yard, or is Karen taking “namaste” a bit too far?
