Spent a lifetime hanging off a ledge

Meanwhile our kind teacher twittered on
Thomas Hardy, Hopkins., we were numb
She never mentioned she saw my escape
The way the nuns  hurt me, the bitter rape

I slipped  on High White Stones and almost  dropped
My feet were dangling off the  fearsome rocks 
No-one knew for I was climbing last
Know me  please but never learn my past

How quickly life has  run since I could climb
Now I merely sit here draped in rhymes
