Yes it does!
And yes, all people suffer at times or places in their lives. The way in which they suffer, and what they make of it, and the way in which they apply it to all else, will be unique based on their own attitudes/inclinations. There are many examples in humankind of people who have endured horrific circumstances and experiences, yet they radiate extraordinary love and joy! I don't think the suffering GAVE them such love and joy, I think they were already inclined toward such attitudes. And I'm guessing that most of us are inclined through our experiences to enhance/expand the attitudes we tend toward.
People who indiscriminately claim that others are only wearing masks of happiness, or are phony, are simply revealing what they themselves do not see, and therefore they must deny the existence of. Imagining that their own "gloom" is actually some kind of great truth that they are uniquely enlightened about. Like sad martyrs... carrying supposed "torches of truth" through the narrow and twisted caverns of their own minds, which they claim to know in detail as they project such limitations onto all else. Yet, ignoring the vast starry sky and all of its light and possibility just beyond their cave entrance.
I am inspired by vastness. To me, it suggests more to love.
