I am a native speaker of Polish, I will be happy to give you lessons/have a conversation. Online or in Kraków. I can also offer lessons in Esperanto (my level is maybe B2). I would be interested in lessons in English, or basic lessons in pretty much any other language. I am especially interested in learning from go/weiqi/baduk players. There are many skills I would gladly accept in exchange, so don't hesitate to message me.
