After some discussion, I heard the guy ask, "Can I have one liter of water right now? They can pull it off during dialysis, right?"
All of us including the nephrologist, the other patients on dialysis and I burst out laughing!
In the same breath, he said, "Doctor, I feel like having six liters of water every day!"
No one except a dialysis patient can understand these emotions.
