A Painting's Glare

She sits there always, watching me.
Slowly I notice, It cannot be.
Her eyes seem to follow, wherever I go,
It's creeping me out, she wants me to know.
She holds many secrets, that, I could tell.
The way she sits upright her gaze never fell.
But gracefully it's obvious, she reaching her time.
She cannot be moved, don't panic, it's fine.
How long does it take to add it all together?
Don't look away now, she's watching, forever.
