Pingus

“But why, if you are so clever, do you lie here like a sack and have nothing to show for it? One time you used to go out, you say, to teach children. But why is it you do nothing now?" "I am doing..." Raskolnikov began sullenly and reluctantly. "What are you doing?" "Work..." "What sort of work?" "I am thinking," he answered seriously after a pause.”
― Fyodor Dostoyevsky, Crime and Punishment
