David was sad to learn from Liebherr that Rafa was no longer working at Solintal, where David enjoyed visiting and working with Rafa. David took pride in helping Solintal succeed through discussions with Rafa over many meals. David always spoke highly of Rafa and Solintal. While people often move on to different parts of their careers, David asked Rafa to stay in touch and maybe meet up again someday to discuss their experiences.
