I also find it amazing that these folks feel secure and comfortable with themselves, to allow us to view them in this highly emotional state.
Crying is as much a part of life as laughing is. When I used to feel uncomfortable in the presence of someone who was crying or in any way, emotional, I learned that it was because of my own insecurity in allowing my emotions to be viewed by others. Holding all of that in for so many years, led to an emotional breakdown which caused me losing everything in my life that made it worth living. While what was lost was never recovered, the good news is that I wouldn't trade who I am today. for who I was back then, for anything.
I've read that crying actually releases toxins from our bodies that build up from stress. It's actually healthy to cry when something like this happens.
I just want to give em all big hug.
