I would be devastated if I found out if my daughter or son donated me their kidney. What kind of father would willingly take a kidney from their child who have their whole life ahead of them...and at that age ? Make peace and go meet your maker.
He should have taken the L, and accept life. A father who truly love their children would never accept this. Shes still 21, she probably didnt think of the consequence coming early down the line. I'm sorry I have to say it, buts it is the honest to God truth.
Ugh, I cringe when people breed kids for that specific purpose. What's interesting is how often people expect female relatives to donate to male relatives-- it's not uncommon for women outside the West to be coerced into giving up kidneys, etc, for their brothers and fathers.
