A tanka is a poem based on the number of syllables per line, or so, I learned this morning from NaMoWriMo.net. The rhythm is 5-7-5-7-7. Here we (I) go.
One Cubic Inch of Bone
Legs ache month on month.
Cut it out, make it stop now.
Pain seems eternal.
Like Civil War Veterans.
Excise Disease. Rest. Relief.
Osteomyelitis.
