this is just to say
i have left
my bicycle on its rack
with the garage door open
you will walk out the door
drive to the store
and buy mint chocolate chip
that will sing in my mouth
take the bicycle down
electronically shut the garage
and remind me again
how i married perfectly at twenty.

This made me smile! I think I like your interpretation as much as (if not more than) the original poem.
