After Kate Spade's death, fans took to social media to discuss how her work impacted their life.

When Robin Williams committed suicide in 2014, Saffo said Spade was interested in the news, saying "she kept watching it and watching it over and over. I think the plan was already in motion even as far back as then."

After multiple attempts to help her sister Saffo said she finally "let go," adding, "sometimes you simply cannot SAVE people from themselves!"
