Step 1: The man is hitting his thumb-nails with a hammer, a painful act.
Step 2: The use of language (uttering curses) serves to express his feelings of frustration and pain.
Step 3: In this context, the man does not require an audience to listen, as the language is simply a personal outlet to release emotions.
Step 4: The purpose here is emotional relief rather than communication with others.
“I put the brown paper in my pocket along with the chalks, and possibly other things. I suppose every one must have reflected how primeval and how poetical are the things that one carries in one’s pocket: the pocket-knife, for instance, the type of all human tools, the infant of the sword. Once I planned to write a book of poems entirely about the things in my pocket. But I found it would be too long: and the age of the great epics is past.”
(From G.K. Chesterton’s “A Piece of Chalk”)
