I SENT...

 I sent my future self a message, years ago

marking poets and poems in an anthology on my shelves 

None of the Above, edited by Michael Lally in 1976

for future reading

Now I am receiving that message,

re-reading these poems I've marked

I am that future self, now, but really

a present one, here and now

The self that sent the message is a past one, now

though present at the time, or so I thought
