Betsy Brooks remembers her father, Charles, as a "razor-sharp" former Marine. The two had their share of arguments, she says. But that all changed late in her father's life, as Betsy recently told her boyfriend, John Grecsek.
Charles was diagnosed with Alzheimer's disease when he was 78. Betsy tells John about her relationship with her dad before, and after, the diagnosis.
"We butted heads from the moment we could," Betsy says.
