In chapter 6:

Mr. Darcy stood near them in silent indignation at such a mode of passing the evening, to the exclusion of all conversation, and was too much engrossed by his own thoughts to perceive that Sir William Lucas was his neighbour, till Sir William thus began --

"What a charming amusement for young people this is, Mr. Darcy! There is nothing like dancing after all. I consider it as one of the first refinements of polished societies."

"Certainly, sir; and it has the advantage also of being in vogue amongst the less polished societies of the world. Every savage can dance."

Ironic that Darcy should be indignant at all the dancing instead of conversation when he seems to think conversation with most of those present to be beneath him. Why should he find one worse than the other? Perhaps because “every savage can dance,” but not every savage can converse well enough for Darcy.
