6. They are happy about your failures
We know that jealous neighbors won’t probably openly tell you that they are happy because you failed, but this doesn’t mean that they aren’t expressing this in more subtle ways. There are many ways someone can celebrate your failure.
Maybe every time you talk to them, they bring up that one time when things didn’t work out for you. More than that, maybe they enjoy discussing things like these when others are around to hear them.
Remember that one time when you bought some new sprinklers, but unfortunately, you installed them the wrong way and managed to floor your whole yard? When that happened, your next-door neighbor seemed to be in an excellent mood.
If you notice that your neighbors change their mood when you are having a low time in your life, you might be dealing with some jealous neighbors.
