what, you mean like pain?
i mean like whatever is stressful enough for a person to take the wall down and show their true colors. For some it’s personal pain, physical, emotional, mental, and it may also include pain they feel because others important to them are in pain, die, etc.
Remember Darwin’s young daughter’s death was the pivotal event that swung him away from God. Lots of people can’t handle that they or their loved ones may/will suffer in this life and they can’t understand how God could allow it.
Granted people in the public eye have to for their own sanity as well as crafting an image, have more than one wall, but this guy took them all down and showed us what kind of person he really is. When it’s done on the internet they have an illusion it’s more private, quiet, and personal.
