Other times, it restores your faith in humanity.
Such was the case for Nathen Steffel, whose daughter Sophia passed away in Cincinnati's Children's Hospital after suffering a hepatic hemangioma in her liver at just six weeks old.
Not long afterward, Steffel told his sad story on Reddit and made a request of other users:
"Since she was in the hospital her whole life we never were able to get a photo without all her tubes," he wrote. "Can someone remove the tubes from this photo?"
And complete strangers took it from there.
They sent Steffel numerous edited shots of Sophia, a gesture that prompted the grieving father to issue a note of gratitude online.
"This is really amazing," he wrote. "Everyone you have made my day. All I wanted was a nice picture. What I received was a lot of love and support from a bunch of strangers. A long with a lot of great photos, drawings and paintings. Thanks everyone!"
Here is a look at some Photoshopped pictures of Sophia, tube-free and beautiful:
