I Dont Understand People

I remember the time I joined a college program. I was only there for a short while before dropping out. But during that time a girl started hanging out with me, which I felt a bit uncomfortable by as I wanted to be left alone. But over a few days I stopped resisting her company and tried to welcome her into my space. That was when she got too comfortable and blurted "ya know I wish for my brother to marry one of my friends" and then just stared at me with a creepy smile and her hands clasped against the side of her face. I didn't know what to say but I curbed my fight and flight response and replied nonchalantly, making it seem like a general statement instead of it being about me. Then I changed the topic.
I dropped out the next day.
