Gas station encounter

This coincidence needs a bit of back story to understand the impact I felt from it. I headed out relatively late one evening to go to the grocery store. The drive to the store from my house basically involves driving south down one road - it's very simple and straightforward, and takes at most 5 minutes (when there's traffic). When I pulled out of the driveway, I noticed that the car was very low on gas. Because my wife was going to take our kids out somewhere the following day, I stopped at a gas station that's not too far from the house to fill up the tank. First, I prepaid at the pump. Then while I was pumping gas, I browsed Facebook on my phone. One story that I read particularly captivated my interest. It had been posted by to an old friend, located quite some distance away, who'd earlier that day watched the police from one jurisdiction in her area carry out a traffic stop in another area, and she had expressed surprise at it happening (e.g. "this wasn't the police for that city, why did they pull this person over?"), and thought maybe the particular officers were overstepping their authority. It so happened that I had particular knowledge of the subject. About 4 years previous, I had been a law student who was working in that jurisdiction (I've since been licensed as a lawyer) and I understood a multitude of perfectly reasonably reasons why those officers could have made the traffic stop. I started writing the reply while pumping the gas, but my gas tank was full well before I had finished. Rather than put the phone away and finish the reply when I got home, I decided to finish the reply there. I sat in my car, writing out the rest of my reply. It probably took me a couple of minutes. Once I finished writing the reply, I started my car, and prepared to head to the grocery story. Before putting the car in gear, I looked at my surroundings to make sure there weren't any other cars moving around in my vicinity (as any prudent driver would do before pulling away from a gas pump). In doing this, I saw that another car had just pulled up right to my left. (For context, this is a very small gas station -- there's just 4 pumps in total). The driver's face inside the car caught my eye, as I thought it looked familiar. I paused for a moment to see who it was. When he got out of the car, I recognized him to be the husband of a colleague of mine. Let's call him Bob (not his real name), and my colleague Mary (not her real name). I turned the car off and got out to talk to Bob. I was interested to talk to him, because Mary was a friend of mine -- we'd both started our career as law students at the firm we worked at. (This was a different firm than the one I had worked at a few years previously.) We went through the student and getting-hired processes together, and even though we worked in different areas of the law, and even different offices (in nearby cities), we remained quite close. Mary, however, been diagnosed several months previous with a very serious cancer (it was already at stage 4 when she first had symptoms), and had been on medical leave for some time. I'd visited a few times, and had kept in touch with how she was doing. The last time I saw her in person was several weeks prior, when she was doing well, and her treatment had been effective. But, within the week preceding this meeting, I had seen a post on Facebook from Bob that Mary was having a tough time. There hadn't been any news since, and I was worried -- Bob had said that she wasn't taking visitors at the time, and asked everyone to give he and Mary some space while she got through it. When I got out of the car, I said "Hi" to Bob. He recognized me and greeted me back. I told him that it was surprising running into him there, and how concerned I was about Mary. Then I asked him how Mary was doing. Bob told me that Mary had died that afternoon. I was utterly and completely floored, in that way that you only can be when the news of the unexpected death of someone you care about reaches you. The best way to describe I can describe the feeling was "jaw-dropping", although that doesn't do it justice. I immediately went over to him and gave him a hug. He was obviously processing a tremendous amount of emotion and events, and he was more than a little bewildered. He told me that the past week had been hard for her, but didn't want to talk about the details. (I found out weeks later that she had been suffering tremendously during much of that time.) He told me that I was the first person outside of himself, Mary's mother and brother, and her medical team to know that she'd died -- they were planning to tell her wider circle of friends and family the next day. He said that he had gone from the hospital to their home to get some things (I can't remember what) and was on his way back when he stopped for fuel. As it happens, the route between Mary & Bob's house and the hospital intersected my route at just this one point -- the gas station. And, as a further (but far less jaw-dropping coincidence), after we had talked for a while, Bob noticed that we were wearing identical shirts. It was absurdly funny at the time that we had on the same colour of nondescript t-shirt from a run-of-the mill clothing retailer. I didn't ask him about the size, but I'd hazard a guess that we're the same size.
