Mrs. Plornish was as proud of her father's talents as she could possibly have been if they had made him Lord Chancellor. She had as firm a belief in the sweetness and propriety of his manners as she could possibly have had if he had been Lord Chamberlain. The poor little old man knew some pale and vapid little songs, long out of date, about Chloe, and Phyllis, and Strephon being wounded by the son of Venus; and for Mrs. Plornish there was no such music at the Opera as the small internal flutterings and chirpings wherein he would discharge himself of these ditties, like a weak, little, broken barrel-organ, ground by a baby. On his 'days out,' those flecks of light in his flat vista of pollard old men,' it was at once Mrs. Plornish's delight and sorrow, when he was strong with meat, and had taken his full halfpenny-worth of porter, to say, 'Sing us a song, Father.' Then he would give them Chloe, and if he were in pretty good spirits, Phyllis also--Strephon he had hardly been up to since he went into retirement--and then would Mrs. Plornish declare she did believe there never was such a singer as Father, and wipe her eyes [...]
Mr. Dorrit was in the habit of receiving this old man as if the old man held of him in vassalage under some feudal tenure. He made little treats and teas for him, as if he came in with his homage from some outlying district where the tenantry were in a primitive state.
It seemed as if there were moments when he could by no means have sworn but that the old man was an ancient retainer of his, who had been meritoriously faithful. When he mentioned him, he spoke of him casually as his old pensioner. He had a wonderful satisfaction in seeing him, and in commenting on his decayed condition after he was gone.

(1.31.4-8)
These feelings about Old Nandy both take the form of pride, but of very different kinds. Mrs. Plornish's pride is aspirational and hopeful – she imagines Old Nandy is a very gifted singer. Dorrit's pride, on the other hand, just runs Old Nandy down – he imagines him a feudal vassal and is psyched to find evidence of him growing physically debilitated.
