Robin Williams once comforted a woman at an airport following her husband's suicide, according to the widow herself.
Writer Kate Lyon Osher wrote about the experience back in 2016 - it's one many tales that depict the late Hollywood star as a kind, compassionate and humble man, despite the enormity of his fame.
After her husband Greg tragically took his own life, Kate decided to take a sabbatical and scatter her late spouse's ashes around the world, according to her piece for The Mighty.
However, when she got to LAX Airport in Los Angeles, security detained her after discovering the ashes and almost forced her to throw them again.
When a distraught Kate went to the airport bar to have a drink and try to calm herself down, however, she heard a strangely familiar voice addressing her.
In her article, she wrote: "A soft voice stated: 'Miss, I just want to be sure you are OK. I see you are traveling alone, and I saw what happened, and I just really want to be sure you are OK.'"
It sounded like Robin Williams, although she initially found it hard to believe.
"Through my tears, I could place the voice but couldn't actually believe Robin Williams was just casually strolling through LAX and would actually take the time to stop to see if I was OK," she continued.
However, it was indeed the Dead Poets Society actor and it turned out he'd seen the whole episode with security as it unfolded.
According to Kate, Williams told her: "'Addiction is a real b****. Mental illness and depression are the mother of all b*****s.
"'I am so sorry for all the pain your husband was in. I'm so sorry for the pain you are in now. But it sounds like you have family and friends and love. And that tips the scale a bit, right?'"
In fact, Williams was actually taking the same flight as the writer and so, after comforting her, he cheered her up by joking about the security guard who caused her such trouble.
The actor of cause sadly also took his own in 2014 after his well-documented struggles with depression, which he never attempted to hide.
This story is one of many that show the actor to be a quietly generous and empathetic man in his personal life. Earlier this year, for instance, it came to light that Williams would stipulate as part of his contract that any company he worked with would have to hire a certain number of homeless people for the project.
Celebrities have also commented on the effect he had on them.
Pink once told a story about how he improvised a 15-minute comedy routine for her after she was devastated to miss out on a Grammy Award early in her career, while Ethan Hawke has always credited Williams for fixing him up with his first agent in light of his breakout performance in Dead Poets Society.
With the seventh anniversary of his death just passed on 11 August, his son Zac paid tribute to him on social media, writing "The joy and inspiration you brought to the world carries on in your legacy and in your family, friends, and fans you so loved."
