Hi PyLadies Berlin! As part of our caring planned activities during PyConDE PyData in Darmstadt this year we will host a **walking guided tour,** inviting participants to step outside the building.

**Topic: The styles of mentoring** Are you an instructor, challenger, sponsor, or a coach? Do you think your mentees learn best with maximum autonomy, or do they need a maximum of guidance?

In diesem Kurs beschäftigen wir uns mit verschiedenen Texten aus unterschiedlichen Bereichen. Das können u.a. kurze Geschichten, Gedichte, Zeitungsartikel, Kolumnen oder Videos sein. Immer sind es Themen, die uns gefallen, die wir besonders interessant, wichtig oder manchmal auch richtig schlecht finden. Gemeinsam versuchen wir die Position der Autor*in, den Stil und die Argumentationsstruktur zu verstehen. Dazu diskutieren wir über das, was wir verstehen, welche Meinung wir zu dem Thema haben oder welche Fragen offen bleiben.
Gerne könnt ihr uns auch Themenvorschläge mitbringen oder zuschicken.
Der Kurs richtet sich an interessierte Menschen mit einem B2-Niveau (oder so ähnlich), die Lust haben sich weiter mit der deutschen Sprache zu beschäftigen und ihren Wortschatz zu erweitern.
Die Termine sind sporadisch.

Ditch the old book club, where everyone has to read the same book...this is better! It works like this: Bring your own book. Come chat, have some tea or coffee, get to know your neighbors. Then we quietly read together, side by side, for about one hour, each one reading their own book, and afterwards we talk with each other about what we are reading. The usual agenda: - Arrival and introduction (~20 minutes) - ⁠Silent reading (~1 hour) - ⁠Discussion (~30-40 minutes) - ⁠Join us for a bite at a local restaurant afterwards, if you like! You may read in any language, you may read any book. We are a group of international residents of Berlin from many different countries, of all ages, and we converse in English. We welcome you! No registration needed – the event is donation based. All funds support the Offenes Wohnzimmer.

Posting this early because seemingly all Sundays in May are holidays or busy! I picked a shorter thriller that's hopefully a fast read/listen. [Columbus library link to book](https://cml.bibliocommons.com/v2/record/S105C3458940) Location: Grandview Cafe, *1455 W. 3rd Ave*, Columbus, OH 43212 [Menu](https://www.grandviewcafe.com/menu) Book summary: Daniel leads a rich life in the university town of Athens, Georgia. He's got a couple close friends, a steady paycheck working for a regional airline, and of course, for a few glorious days each Fall, college football tailgates. He considers himself to be a mostly lucky guy -- despite the fact that he's suffered from a debilitating disease since he was a small child, one that has left him unable to speak or to move without a wheelchair. Largely confined to his home, Daniel spends the hours he's not online communicating with irate air travelers observing his neighborhood from his front porch. One young woman passes by so frequently that spotting her out the window has almost become part of his daily routine. Until the day he's almost sure he sees her being kidnapped.
