I keep seeing the same guy near my workplace and now I’m not sure if it's a coincidence

For the past couple weeks something kind of weird has been happening and I honestly cant tell if I'm overthinking it or not. I work in an area with a lot of small businesses and apartments, so there are always random people around, and because of that I normally don't pay attention to strangers at all, but about two weeks ago I noticed this guy. The first time I saw him I was leaving work in the evening and he was standing across the street near a bus stop just looking at his phone. Nothing strange. I walked past and didn’t think about it again.

A few days later I saw him again about a block away from my job near a convenience store I sometimes pass when I go get lunch, and i only noticed because when I walked by he looked up at me for a second and then went back to his phone.

Still not that weird.

But after that I started noticing him more often.

Once he was sitting on a bench near a coffee shop on the street behind my workplace. Another time he was standing near the same bus stop again. Every time I saw him it felt like he noticed me, but not in an obvious way. Just quick glances, at first I assumed he probably lives nearby or works somewhere in the area, then last week something happened that made it feel a little stranger.

I left work almost an hour later than usual because we were closing late. My schedule that day was different and I figured most of the usual foot traffic would already be gone, when I turned the corner toward the street where I usually walk to the bus stop, I saw him again. Same guy. Same dark jacket I had seen him wearing before. He was leaning against a wall and when I turned the corner he immediately looked away like he didn’t want to make eye contact. That was the first time it gave me a weird feeling, mostly because my schedule that day was different so it felt like a strange coincidence, and after that I started paying more attention when I was outside near work.

Since then I've seen him a few more times. Once near the convenience store again and once walking down the same street I take sometimes when I leave work. Another thing happened a couple days ago, i was leaving work and decided to stop at the convenience store, and when I walked in I noticed him near the back of the store looking at something on a shelf, but i didn’t think much about it and grabbed what I needed. But when I got to the counter to pay, I glanced toward the front windows and realized he was now standing outside the store, he wasn’t looking at his phone anymore. He was just standing there. I paid and waited a minute pretending to check something on my phone because I didn’t really want to walk out at the exact same time and after about thirty seconds he walked away down the street.

The thing is he’s never approached me, never said anything, and I’ve never actually seen him follow me anywhere, he’s just… around, often enough that I keep noticing him. Part of me thinks I’m just seeing the same person who happens to live nearby and I’m connecting dots that aren’t there, but another part of me keeps thinking about how many times I’ve run into the same person in slightly different places around my job. Maybe it’s nothing, but it’s started to feel just weird enough that I can’t stop thinking about it.
