" The unsaid rule for living in a trailer park is: ‘If the door’s shut, don’t come a-knockin.’ But if it’s open and you’re walkin’ by, feel free to say, ‘Hello.’ "
- Matthew McConaughey

In simple terms, this quote suggests that when visiting a trailer park community, it’s polite to respect people's privacy by not knocking on closed doors unless invited. However, if someone has their door open and you happen to be walking past, it’s okay to greet them or drop in briefly.

Delving deeper into the quote, Matthew McConaughey is emphasizing the importance of social cues and respect for personal boundaries within communities. The idea is that when people leave their doors open, they are inviting conversation and interaction, creating a sense of openness and community spirit. This can foster better relationships among neighbors by encouraging casual interactions. Conversely, closed doors signal that someone may prefer privacy or solitude at the moment, which should be respected. Ultimately, this quote speaks to the nuanced nature of social etiquette and how it can vary based on subtle signals from others.
