It’s called “telling the truth.”
Evidently you consider that to be aberrant behavior.
What's the problem, you lost your Sense of Humor in a Tragic Boating Accident?
Just so you know, I had to receive Blood Transfusions for an entire Month due my Leukemia making a comeback.
Six Months later, I get a call from my Oncologist telling me that the LAST Pint of Blood I received came from a Donor who had come in to give Blood again and they had Hepatitis C. I had to see an Infectious Disease Specialist and get tested. Lucky for me the tests came back Negative so the Donor must have contracted Hep C after the earlier Donation that I received. Tell me, how does someone get Hep C, especially someone who regularly Donates Blood and who would most likely be very careful, or so we would think?
