"...ability"

This is a scene from the 2001 HBO production of “Wit”. A very moving film to watch. It speaks to what so many of us have experienced. A loved one nearing death. Many of us have been care givers to both family, and friends. To you there’s nothing I can say that you don’t already know. No doubt many of you were braver, and wiser than me, but we all did what we had to at the best of our ability. 

…death, thou shall die.
