Wow. We feel like we won the neighbor lottery !!!! Everyone, and I really mean everyone on our street is friendly and never fail to wave, smile, stop to talk and pet our dog, invite us to go out to eat or play cards. This place has been everything we hoped for and MORE. We would do anything for our neighbors and they would do the same.
My advice to you is turn the page and make a fresh start. Like other suggestions, go out of your way to invite a neighbor for coffee or to play a game. We have made new friends at the bocce courts, playing golf, and attending neighborhood parties. I have found that our dog is a GREAT way to meet people. Most want to play with him first
Can hardly walk down the street if he is with us because people come out to pet him. We don't mind. Just another excuse to talk to the neighbors.
Hope it turns around for you.
All the best.
