Personally, noting my background, I can certainly relate to this drabble. Back in the day, when I was living in San Francisco, I was a CNA. It didn't take me long to discover the job wasn't for me. It's not for everyone.
You're story is highly compelling. I am sure there are other readers here that have, noting the experiences your character faces, can draw lines between their own lives and what is written here. Nicely done.
