I can't remember what I did with my gum

Did I have it when I sat down at the computer?
Was it with me while I dyed my hair?
Is my puppy chewing on it now?
Why can't I remember what I did with my gum?
I had gum in my mouth, about an hour and a half ago.
Now I no longer have gum.
I am frightened. I am worried.
It could be anywhere.
You would think I'd recall spitting it into the trash.
Or wadding it up in tissue.
Some act of disposal, since it is absent.
Yet nothing: just the memory of gum, and
An empty feeling, like I misplaced my name.
