Back in about 2001, came home drunk one night as a teenager and went online. Met this guy in a chatroom, talked to him til about 6am. Made immediate plans to go visit, bought train tickets the next day.
Iirc it took 3 trains to get to his town, I remember an older lady chatting to me and seeming very concerned when she heard what I was doing (in hindsight, I see why haha).
Honestly we didn't really vibe irl and so it turned out "awkward". But I didn't get murdered, which frankly is a bit of a miracle.
