1. If you bring beer or any alcoholic beverage to a party or to just a get together never ever take it home with you when you leave. Its extremely disrespectful.
2. If your friend shows up with a female never ever make him look bad or never hit on her. Your job as a FRIEND is to make him look good.
3. A man should never ever ever sit next to a man in a movie theater. Its looks mas puto.
