A couple small details first — that 3rd stanza's the weakest with those gerunds in use there at its heart; in the 1st stanza, trustworthy shouldn't be hyphenated as well as a missing apostrophe in liar's in the 4th stanza. It's that 3rd stanza that should prove to be the most difficult to tweak.<P> Other than those little details, you show so well the difference between the gross obvious signs over which a person can control {voice, mouth, & gestures} and the more subtle signals that cannot so easily be controlled {the eyes}. I'm sure most people can relate to this difference.
Sometimes we do not want to know the truth but when we do, stare at his eyes to see if he blinks.
Good job.
