They were married for 68 years and they died just one day apart

"The death of his father coming so quickly after his mother's seems like much more than a coincidence to Brent. "When I asked him what his wishes were if mom passed away, he said he couldn't imagine life without her. And in the end, he was right," Brent told CNN." 

This represents pain because a family is experiencing not just one loss, but two within two days. The man in this couple could not bear to live without his wife, so he passed just one day later. I believe this represents the pain of losing someone, and not being able to handle it. Although the husband's death was peaceful, he was emotionally in pain which likely caused his sudden death.
