Your correspondent was staying with an old Quaker friend in Maine and her 11 year old grandson came over one evening for an overnight visit.
The grandson had decided to learn Yiddish, the language spoken by the characters in Art Spiegelman's graphic Holocaust family memoir "Maus" after reading and becoming intrigued by the narrative. (Yiddish, an amalgam of German, Hebrew and Aramaic used by the Jews of Eastern Europe and Russia since before the 12th century suffered a serious decline with the near extermination of its speakers during World War II.)
So I eagerly introduced the grandson to some choice Yiddish expressions I learned from my grandparents and the next morning I wrote him a letter incorporating those words in context. I suggested he read the letter aloud to Grandmom for practice and they indulged me in letting me video them.
