I'm trying to identify a short story on which the Black Mirror episode "White Christmas" might have been based. Or at least is very similar.
In the story, the protagonist was regularly visiting a park (or was working in it), the same time every week. Each time he was there, he was looking at a woman, with similar schedule, he desperately tried to contact (or was in love with). The problem was, he was convicted of a minor transgression — which caused him to be blocked/blurred when seen by other people. Similar to the Black Mirror episode.
If I remember correctly, the woman didn't wear her AR lenses — which made her see him as a normal person. He knew that approaching the woman would be pointless, as he would only be able to talk to her until she put on her lenses.
The story might have ended with him approaching the woman. When strolling around the park, she decided put on her lenses, and saw her companion as blurred criminal. When he tried to explain to her that she shouldn't be afraid, she pushed him in panic, causing him to fall and hurting himself. She was convicted of assault and became blurred/blocked herself. In the closing paragraphs of the story, she was visiting the park the same way the man was doing — being blurred to other people.
The punch line of the story pointed to the extreme, cruel, and often unjust stigmatisation caused by the AR blurring.
The story was port of an scifi anthology. I'm wary of giving more details, as I'm not sure as how much of my recollection was biased by Black Mirror.
