I will admit right up front that I am not a poetry connoisseur, but every once in a while I read a poem that stops me in my tracks. This one, by Juan Ramón Jiménez, is one of those poems:
I am not I.
I am this one
walking beside me whom I do not see,
whom at times I manage to visit,
and whom at other times I forget;
who remains calm and silent while I talk,
and forgives, gently, when I hate,
who walks where I am not,
who will remain standing when I die.
Juan Ramón Jiménez
