You are the master of your life! Make a block party to make neighbor friends, go to a park on a weekend, take a bus (yes, you can't start a conversation at a bus station if you only drive), travel to different US cities.
This. I used to live in Seattle after vacationing there a handful of times, but after living there I found it to be one of the most least welcoming, racist, Progressively Elitist™ places I've ever lived (and I've lived all over the US).
It's easy to say "I will commit to making more meaningful connections with people/strangers today", but if this is not received or reciprocated; well...there's not really much you can outside of devoting more time in trying to breakthrough some sort of glass wall that some places have created an environment for. Which comes down to two choices in my book:
1. Fight through and prove yourself/others wrong 2. Go somewhere else that you feel will be more accepting
