I don't profess it to be a sonnet in the technical sense! I am using a certain amount of poetic licence, you understand...
I sit, but not in quiet contemplation
My mind too steeped in lethargy for dreams
All vim and vigour in incarceration
I look pensive; but it is not as it seems
I have no thoughts revolving round my brain
I concentrate my will to stay awake
Force my eyelids to stay open, but in vain
And so I fall asleep, for sweet sleep’s sake
The day to me is dreary and endless
The prospect of the evening, no allay
I watch the day pass by me, known, yet friendless
As is my idle choosing on this day
A trait in others I have many times abhorred
I am neither ill nor lonely. I am bored.
