Yeah, I got a bit lucky, because the guy I talked the most to initiated the conversation, very intelligent interesting guy, so really enjoyed that interaction.
Besides that talked to 3-4 other people who were also sitting in the same vicinity and overall had a very pleasant evening. When I arrived there, I wouldn't have expected that I'd be one to stay until the bitter end (3-4AM). But I did it and am glad about it, although I'm really happy that my crush was also there, because it's always easier, if you know someone.
So thanks to the Bernds who encouraged me. Next step might be going to ans rave or festival some time, do some drugs, explore things I have never done before.
