How do you say?

This frustration with language is nothing new.
I learned to say when I was two:
"I show you! I show you!"
(and quickly too).
Because without those words I knew
my message wasn't getting through.

And now I'm twenty-two,
and my face is turning blue
searching for a word, a drill, to screw
all the wrong words right through—
the rusted words—for all they do
is keep me walled from knowing you.
