Would you ever walk up to a total stranger and strike up a conversation?

Yesterday I was at a restaurant with my friends. This Asian guy came in and sat near us. I noticed him speaking Korean on the phone. I consume a lot of Korean content, so this got me really excited. On a whim, I decided to go up to him and chat. I introduced myself, and he invited me to sit with him if I wanted to, even though he was a bit awkward, lol. He ordered some stuff for me. I found out he’s here in Switzerland for work, and we had a good talk. I ended up hanging out with him around the city. We exchanged contact info and are seeing each other again today after he gets off work. It was my first time doing something like this, and I honestly didn’t know meeting people could be so spontaneous and organic.
