Told us all these amazing stories about her f*cking incredible life, some of which I did, sadly, not commit to memory the way I should have.
Tried to speak some German with me which she had learned from her mother (my ex-sister never learned German).
Told us about Tunisia, and in general all the things that she had learned while working for other (oftentimes richer) people.
Read books. All the times, books. Books books books. She had tons of them.
