siercia | Weird train encounter

So today, took the train into Harvard Square for a dentist appointment. Waiting in the station for the train to come for the ride home, there was a guy there, and he kept talking to other people. I couldn't quite hear the conversations, they seemed innocuous enough, but I couldn't really tell. The guy was a little unkept looking, but that was all.

The train came, and I sat down. And the guy came and sat right next to me (the train was getting full so it's not like he did it in an empty car). And I'm not sure why, but I got such a weird vibe that I did something I never do - I got up and changed seats. When he realized what I was doing, he started to get up too, like he was going to say that it was fine if I stayed, he would move, but by then I was already half a car away. He just sat there looking kind of dejected for the rest of the trip until his stop came.

And I'm wondering if I was right, and there was a weird vibe going on, or if I was just horribly rude to some poor tourist who had only been asking for directions in the train station, and thought I looked friendly enough to sit next to on the train. If he'd been closer, close enough to hear me, I probably would've apologized, making up a tale about not liking to sit right next to men on trains, but I couldn't.

It'll probably bother me all night.
