We got a new car and within a month the neighbors had the same car in the same colour, I didn't think anything of it as I thought it was a coincidence. We recently renovated our driveway in a design that I'd designed myself, the neighbor said she was going to do the exact same to hers, I thought she was joking so I just smiled, little did I know, she wasn't. She got the same company to do hers with the same stones and plants. I was really upset as I'd wanted ours to be unique.
I've tried to be friendly with her but I feel like she's just too much, she mentioned that she has emotionally unstable personality disorder and now I feel bad for being annoyed.
