This is the poem for today in Poem A Day, ed. K. McCosker & N. Albery. It seems very appropriate:
I Am Not I
I am not I.
I am this one
Walking beside me whom I do not see,
Whom at times I manage to visit,
And at other times I forget.
The one who remains silent when I talk,
The one who forgives, sweet, when I hate,
The one who takes a walk when I am indoors,
The one who will remain standing when I die.
—Juan Ramón Jiménez, translated by Robert Bly
