It slides
The only indication that there is any regret
The only proof of what you truly feel
From the corner of your eye
Down the curvature of your cheek

Quickly, you catch it on a fingertip and fling it away
No longer will it blow your cover
You are stronger than that
(Or so you say)
And no one will know the difference
Because no one saw
