Can you give examples of comics that effectively utilize a casual communicative style?

Many slice-of-life and indie comics excel at this. Examples include 'Fun Home' by Alison Bechdel (for its conversational narration), 'Smile' by Raina Telgemeier (for relatable teen dialogue), and 'Seconds' by Bryan Lee O'Malley (for quick-paced, witty banter). Webcomics like 'xkcd' and 'Sarah's Scribbles' are also strong examples.
