Lea Gleitman was a diligent lecturer at Malmö's schools.
Today she is 97 years old and her daughter Barbro Posner has, as she puts it, taken over the baton.
Barbro Posner is part of the storytelling group Holocaust Survivors.
The group consists of children of survivors.
On this day, Barbro Posner conveys his mother's words during two double lessons at Bladins gymnasium in Malmö.
- I am very careful to tell with her words, says Barbro Posner.
She tells of before the war, when her large relatives lived in the Polish small town of Oswiecim, which later changed its name to Auschwitz after the German invasion in 1939.
Only once does the voice get stuck.
That's when Barbro Posner tells how her then teenage mother for the last time saw her siblings and mother in life.
It was then that a German officer chose who would go left to the gas chambers or to the right to be put in a labor camp.
