Oh, no. This person’s neighbor might have a spy camera pointed in the direction of the OP’s backyard. However, the Karen here has no proof that it’s even a spy camera. From what we can see, it looks suspicious object looks incredibly similar to an ordinary sunflower.
That’s because it is an ordinary sunflower. There’s nothing suspicious going on here, except for the OP’s growing paranoia about people wanting to spy on them. And why can’t you just knock on your neighbor’s door and ask them about the plant? We’re guessing this Karen already ruined their relationship with the neighbor following past complaints.
