I'm in Germany, how do I find somebody to have some chit-chat?

[Henry]

I've had 1 year of German lessons and would like to have a real talk with somebody. There's a park nearby but I always feel too much stress to just begin talking to a stranger that might just ignore me and I have no idea what to say! And I must already find somebody who is alone, because talking to pple who aren't alone is awkward lol.

Thanks
I'm on holidays here for 4 more days, i mean I've had lessons about the German language and now I'd like to speak some German
