We aren't friends, just happen to be neighbours. She increasingly copies what I do/what I buy. Her child even has the same name as mine (my dc is 2y older). She's copying more and more personal things now, and it's just starting to boil my piss. What's especially annoying is that when we do speak, she's very snarky about my house/dcs - very passive-aggressive, low-level, but present.
AIBU? If not, how do I deal with it? other than move
