I suck

I suck at this , that , those,  writing prose;
pretending to know , yet not knowing  but smiling 
yet not smiling,  a dead-eyed doze ,  feet tapping
a thousand tap  tap tap -dance , jiggling knees , twitching toes
eyes flicking  flickering , bony elbows
digging in ,  scraping on sandpaper pillows.
