You are terrified of growing old and having things sag;
  I am terrified of growing old and saggy without you.

Mirrors are deceptive minxes
Gleefully making you insecure
When you're thin in a gown
Yet lumps  unfold in the mirror's glare.

Thighs curved and tight in those jeans
Become a large and saggy reflection; mocking
Denial isn't an option
Not when the evidence is right in front of you.

You fall for the mirror's  deception
And try to get rid of the imperfections
Diets and exercise but it never changes
The imperfections keep building up
No matter how hard you try.

Now the dresses and jeans fall off
Barely hanging on
Yet the lumps and skin are still there
When you look in the mirror; ashamed.

Your twin shows no change
Forget doctorly concern; weight machine readings
You have to work harder; erase the faults
Because the mirror never lies does it?
