Half a Wave

Caught between polite and proud.
Half a wave, half aloud.
Saw him at the barber shop last week,
He sat three chairs from mine.
We both pretended not to notice, both of us were lying fine.
He probably knows my favorite drink,
The way she talks in her sleep.
Do I act like that don't matter, or just keep my peace?
Half a wave, half a smile, half the man I used to be.
Should I look him in the eye, or just let him walk on by?
Half a wave hanging in the air, neither here nor anywhere,
Caught between polite and proud.
