The Inside of my Eyelids

My friend told me to write about the inside of my eyelids
after conducting thorough research on the subject.
Always up for a challenge, I immediately read up on eyes;
or at least tried to, squinting with one of mine against a ferocious migraine;
the other one shut tight.
Now, I'm not normally one to miss people's intended layers of meaning,
but I'm tired and spent after a stressful couple of days.
I was all ready with my smart-arse comments about
conjunctiva and sclera and blood vessels...
but apparently I was meant to thoroughly research the subject
by going to SLEEP for a change. Stop, woman!
Oh.
I was hoping to last the month without resorting to writing about what to write about,
but desperate times are famed for relying on desperate measures.
