DEAR ABBY: I have two sons, 19 and 12. My younger boy has a rare form of kidney disease.
His kidney function is now normal, but his doctor says that in the future he may need a new kidney. At that point, his brother would be high on the list for compatibility and availability. I, sadly, would not.
How does one mention the possibility of being a donor to his older brother? Is it even fair to ask? If he doesn't offer, would I always resent it? Should we wait until there is a real need before asking?
