I Used to Think

I used to think when people died their images would fade,
their color pictures change to black and white then grey,
their spirits hover like the light at nightfall.
After his fatal heart attack, I felt Walter tethered
to the earth, revolving like a moon in orbit
or were we revolving around him
who felt alone out there?
But when you died I saw nothing.
The sun eclipsed, the moon
went dark, and an absence grew
so vast a continent appeared where I now live.
