Its probably just bad luck. I rented a house close to La Costa Canyon HS on Corte Del Cruce. We moved in and one neighbor brought us a bottle of wine. Another brought us a list of all the neighbors “close by” that included names, kids names, phone numbers etc. We all waved at each other when we pass by etc. It was very friendly.
Maybe consider having a little get together at your house and get the friendly neighbors to encourage others to come. Maybe put together a progressive dinner type deal. Maybe use back to school as an excuse.
