Yes, I do. I cry sometimes when alone especially if I have something weighing me down emotionally. In such scenario, I just prefer to let out the pain by crying it all out, instead of bottling it up on the inside, because doing so would make the pain to be worse. However, whenever I cry, it must be something that has really touched the deepest part of my soul.
I know it might sound weird to many wondering what could cause a man to cry, but I don't see it that way. Manliness is not as result of being unable to shed tear or show one's side of vulnerability, but the ability to recognize we all have weaker part of us, that the world does not know of. As I always say that vulnerability is not a sign of weakness but of strength.
And so, if you're a man you think is not appropriate to cry, but believe me, it's a facade of emotional susceptibility displayed by such a person claiming to be strong, but in the real sense, the person is weak.
