My sister is an extrovert and has about a small village worth of friends. She used to hold parties before she had kids, and would invite me. I'm an introvert so would dread these, but always ended up enjoy going when I did. One day she called me the day after such a party to say it was nice of me to come, as she would, but added "everyone always enjoys it when you're there, you're so good at making people feel seen". I got really taken aback by that. I hadn't thought about that at all, I was just coping with my social anxiety by asking people questions. Years later I was at a family function, and a relative had a new girlfriend from the US. I noticed not many talked to her except her boyfriend, so I sat down and started to ask some questions. We ended up talking for several hours until everyone else had left. At the end when it was time to go to bed, she suddenly started crying. We asked what was wrong but she just said "you have no idea how good it was to just talk to someone". She'd been in the country for a couple of weeks at that point without really having anyone else but her boyfriend have a conversation with her, despite meeting his family and such many times. That also moved me. While I had noticed she was a bit alone that evening, I hadn't considered how much it could mean to her. I was just thinking she would be interesting to talk to being from another country, and figured she might be a bit bored so hopefully I could alleviate that. Again, I don't feel like I'm doing anything special. I'm curious so I like discovering new stuff. I try to find what people are passionate about, as that's almost always something I don't know a lot about and so I can discover a lot of exciting new stuff. And doing that helps me overcome my social anxiety. However, I do try to listen to people and I try to respond thoughtfully. How else can I have a meaningful conversation?
