WHO?

I was looking for you, he said,
and I was looking for myself
she replied, and here we are
and neither of us has succeeded
in our quest, for I have not
found myself, so you cannot find me.
I shall stop looking for you, he said
and perhaps you will appear.
for I am ready if you choose to.
I have found myself, finally,
she replied, but how long
have you been standing there
and what were you doing
since I last saw you?
