Recently I met up with a guy from a dating app. We've crossed paths, online, over the last few years. I don't remember exactly when, but at least 5 years ago must've been the first time. I don't think we spoke, or if we did it was brief. We were working in the same area, but never crossed paths. I was on a casual contractor basis, and on one day I was asked to work at a site, which happened to be the one day that week that he visited that site. I remember recognising him. While the chances of that happening were small, it was still in the realm of possibility.
