The meanings changed

From the first word that I said to the last
some strange echo remains
imprinted in the walls
recorded in the vaults
we talked and tunneled through
but the meanings have all changed.

Because of all I said
you began to regard me as strange
until with some relief
you suspended disbelief
I tried to tell the truth
but my meaning was all changed.

I saved one final word
to pay off this long sentence in spades
but what I thought I said
was patently misread.
The spoken word
is broken here
and in between the two of us
the meaning is all changed.
