Both of these excellent characters are flat characters, in that they only have two or three attributes and never develop or change as the novel progresses. The Aged Parent is noted for his deafness and his love for his son and the pride he has of him. This of course results in hilarious scenes when his audience has but to nod to communicate with him and the difficulties that anyone has in engaging him in any topic of conversation. Consider the difficulties that Pip experiences:
As I could not sit there nodding at him perpetually, without making some other atttempt to interest him, I shouted an inquiry...
Miss Skiffins is presented as another larger-than-life Dickensian character who is notable for her woodeness and her fondness for garish colours in her dress:
Miss Skiffins was of a wooden appearance, and was, like her escort, in the post-office branch of the service. She might have been some two or three years younger than Wemmick, and I judged her to stand possessed of portable property. the cut of her dress from the waist upward, both before and behind, made her figure very like a boy's kite; and I might have pronounced her gown a little too decidedly orange, and her gloves a little too intensely green.
She is thus introduced as another flat character in this chapter who is notable only in terms of her relationship with Wemmick and the happiness that he manages to attain outside of his work.
