I thought I don't have a story, but I just remembered one :)
End of may/beginning of june I spent a few weeks in the desert at MidBurn, the local israeli burning man. Some people that I worked with there knew that I am half polish. So at some point, a guy I know shows up and says: "There is this polish friend of mine that you have to meet". I went for it.
A few moments later I met Mateusz. Talked a little bit with him, he told me that he lives in Wrozlaw. I told him that my mom and her family used to live in Walbrzych. Turns out that he grew up in Walbrzych. I then proceeded to tell him in which part of the city. Turns out that he also used to live there. Then the street, he lived 2 blocks away...
I then asked him where he went to school. And then who his biology teacher is.
Turns out his biology teacher my mom's best friend that she had since high school. And there we meet in the desert in Israel.
