Can I text my female neighbor that they're a fucking cunt?
Are you really going to text that?
It's under consideration, but what I'm thinking about is writing "Josie, you're the most selfish person I've ever seen.. Go to hell! You're dead to me."
It's rude to tell someone off through a text. If things get worse she could use that as evidence of you harrassing them.
Let me remind you that you can't know how she will react to this.
Neighbors have to deal with each other on a regular basis. It's better to maintain a healthy relationship instead resorting to harassing one another. Your home life may become more difficult and toxic if you're surrounded by neighbors that dislike you.
