Been there done that, in New Orleans, where I'm from. People gave me the side eye for the first week or so, but pretty soon I was just one of the folks. Dancing at block parties, eating yummy soul food at the family-owned restaurant on the corner, exchanging nods on the sidewalk, singing in the church, etc.
Never once felt scared or uncomfortable because New Orleans is majority Black so there are plenty of opportunities to be the only white person in the room. So I was kind of used to it even before I moved to the projects (due to financial constraints stemming from disability and single parenthood.) Pretty soon the kids were speculating that I wasn't "white," I was "bright-bright." (I recently took a DNA test and found that the kids were right! However, I was raised white, look white, and get treated like I'm white, so who cares what 23 and me says?)
My family refused to visit me at my home. Instead, they insisted that I meet them at a major intersection in a nearby commercial district, and then they would drive me to their home. This always embarrassed me and I told them so, but they kept saying they didn't feel safe. I hoped that the neighbors wouldn't notice this little charade. (They probably did but they never mentioned it to me, probably out of kindness.)
Contrast this with how Black people are treated when they enter white spaces. Sundown towns, white flight, Karens running wild ... it's a lot more dangerous the other way around!
