It is from a Mary Oliver poem "Sometimes" from Red Bird.
Here's the thing. I like to read Mary Oliver (and Sandra Cisneros, Naomi Shihab Nye, Maya Angelou, Cathy Song, Juliet Kono) when I need a little inspiration. So at this time, in this place, this is what I needed, so I stole it.
My husband is caring for his mom and my aunt is in the early stages of Alzheimers. On that side of the family, they all got Alzheimers and my aunt is the oldest sibling of my father, so I think there is a good chance that I will eventually get it too. Because of that, I have been thinking about how to live the life I have now, and then this came and I realize that this is how I want to live for as long as I can. I don't need to be able to drive, to be mobile, to even remember. I can still pay attention. Be astonished. Tell about it.
