In the following example: "Always the same with you Nancy, 'Clean up after yourself, ya dirty old fool--blah blah blah--If this place isn't spick-and-span by tonight...' I'm just sick of you bossing me around!" How would I punctuate what the main character's mimicry of what Nancy might say. Would I use single quotes as I've done there? Italics? Something else? Thanks.
