"Neurotics build castles in the air, psychotics live in them. My mother cleans them"

This quote by Rita Rudner is an amusing way of describing the differences between neurotics and psychotics. Neurotics are individuals who are extremely nervous and tend to fret excessively. They develop castles in the air, meaning they produce impractical expectations and objectives that are challenging to attain. Psychotics, on the other hand, are people who experience extreme mental disorder and often have delusions and hallucinations. They reside in the castles in the air that neurotics have actually created, suggesting they are unable to distinguish between reality and fantasy. Lastly, the quote suggests that the speaker's mother is the one who cleans up the mess produced by the neurotics and psychotics. This could be interpreted as a metaphor for how the speaker's mother is the one who is always there to help and support them, no matter how challenging the scenario might be.
