Input: Went to see "Us" by myself last night in a theater. (It was awesome, by the way.) Got in just as it was about to start. I see a single open seat in the middle of the theater, middle of the row, just next to the walking path to the other side... I hope that makes sense. There were a group of three ladies on one side, and a couple (young, female next to the seat, male next to her). It was a small theater and was mostly full except for a handful of end-row seats. The whole row looked like this:

 (More seating below)

So I asked if that middle spot was available, and the girl of the couple moved her purse out of it for me. I said thanks, sat down, then her dude said:

BF: Aren't there any other seats?

Me: Uh... sure, there's one next to you and a couple up there. Why, do you not want me to sit here?

BF: ...It's just weird. 

The movie was just starting so we both sat back. But I guess I just didn't understand why it was weird. I am pretty fluent in social norms. I'm also 36 and don't mind seeing movies alone. To me, if there's an open seat in a full theater, I'll take it. I felt like it was weird that he thought it was weird. I told myself that he's just young (probably around 20) and naive.

Context: I don't smell bad, don't look like a threat. Just a normal dude. After the movie, they left first and there wasn't a word between us. But I just can't shake it and wanted some outside opinions.

Should I have not taken the empty seat? Was I the asshole?
