This is the first I've seen a post so detailed about their personal life that it's beautiful to read. It's a personal reflection and so real. On my perspective, I usually play the role of the health are providers in stories like yours, cause, well, that's really where my career is going. I only get to know my patients based from the present history why they came to the ER and would usually know more about them when I make rounds in the wards or private rooms. 

I would often overhear conversations like the ones you mentioned along the hallway when passing through the ICU. It's horrible to think I have become used to it but it's also a must need to get used. Each person has a sad tale before they come to the ICU or ER.
