Shawn Glenn never told his 13-year-old daughter, Symaria, that he was dying. He refused to explain to any of his children that he was going to kidney dialysis appointments three times a week. He didn’t want them to worry, or worse, to research his condition themselves — and perhaps see the average life expectancy of five to 10 years, then decide to donate one of their kidneys to him. “It was a sacrifice,” Glenn said at a news conference Tuesday in the transplant wing of Memorial Regional Hospital in Hollywood.
