In "Great Expectations" describe the man Pip met in the churchyard.
The man that Pip meets in the churchyard is someone who will significantly change Pip's life; the meeting itself is intense and anxious. He is an escaped convict who had managed to elude the authorities on the convict boat that was harbored near Pip's town. These boats transported criminals from one place to another, and the convict had escaped and swam to shore.
Dickens describes the convict in great detail--one of the strengths that Dickens has an an author is the ability to describe characters in a such a great way that it is easy to feel like you know them and can see them yourself. Here is the description:
"A fearful man, all in coarse grey, with a great iron on his leg. A man with no hat, and with broken shoes, and with an old rag tied round his head. A man who had been soaked in water, and smothered in mud, and lamed by stones, and cut by flints, and stung by nettles, and torn by briars; who limped and shivered, and glared and growled."
It is a picture of a wild and desperate character, and indeed he is--he's on the run from the law, starving and bruised, and barely holding on. Pip, in giving him food and assistance, does a great deed for him, one that will not go unpaid. I hope that helped; good luck!
