Sorry Tishie! Sometimes it is a hard subject just yesterday I was laying in bed and could hear the gardeners using a weed eater and gardner was giving the motor spirts of gas. The people operating the motors (before they started using Zyclon B which did not require a motor) would start and stop the motor as needed until the patients were dead. Even not having been there, the sound of that weed eater was a little much. Had to leave the apartment. So even hearing the testimony about the sound of the motor, knowing that sound would be the last they would hear sets me off. How do people know all this stuff? The Nazi's kept very careful records. And that Zyclon B gas, was manufactured by a company called IG Farben, a now defunct division of Bayer! Yes, that Bayer. So how many of our caretakers used Children's Bayer asprin cool our fevers? Bayer is banned from my house.
