Undiagnosed

"I don't know why," you say so casually, not even breaking your step

"They say you gain weight with puberty. That's not true. You slimmed right down."

I stumble and stare

Recalling the hours of exercise

Of calculating calories so breathlessly

Of forgetting what hunger feels like because it's just the constant state.

You don't know about that, but I wonder how you could

Not know.

I knew you missed it, but I didn't know it was by a mile.

By a galaxy.
