Basic social etiquette rules:
Always be on time for dates and get-togethers. Showing up late is rude and shows a lack of respect for other people’s time.
Make eye contact when you are in a conversation with someone. Avoid looking over the other person’s shoulder unless you see potential danger.
Never interrupt the other person.
Give and receive compliments graciously.
Refuse to gossip with and about friends. After all, if you share gossip with someone, that person will wonder what you are saying behind his or her back.
