That Mysterious Off Switch

but I seem to be missing that mysterious off switch that makes people say, 'That's too sweet!' or 'I can't eat all that.' ~ Miranda O

Where is my off switch? Am I a mutant,
lacking vital parts? Why don't I function that way?
People seem so weird! The things they say!
How the heck can anything
be too sweet? How do you leave it on the table,
maybe nibble a bite, and never think of it.
Oh, not touching I understand. But even then
the cravings, the obsession, the sense of entitlement
should blossom, bloom, control!
Is it really possible for anybody,
actually, to be just too full for another bite?
But more important, if these folks have a switch,
something always there, allowing them to stop
despite there being more, and nobody looking,
is there some such switch permitting them
to turn food down, to walk away?
If there is such a switch, I want it.

But really, I understand.
It exists, but not for me.
I am a compulsive overeater,
and I'm powerless over food
and my life's unmanageable.
