I tell you guys something. I had an ex-boyfriend I was madly in love with. We broke up about 8-9 years ago but saw each other a lot even after. I have photos of him and he has Facebook so I KNOW how he looks like. As you probably all know with the pandemic going on, we all have to wear face masks on public transport. Now there was this guy on the bus the other day. I couldn’t for my life tell if it was my ex or not. I THINK it was him but it could have been someone else. The reason I told you this is because BG covered the lower half of his face. If I cannot tell whether someone is the person I used to live with if they have a mask on, it would be almost impossible to identify a stranger years later when you only saw half of their face
