1. Any appointment or gathering should be communicated in advance, with prior notice and invitations sent out. Last-minute invitations in the United States are considered "optional" and are extremely impolite.
2. After receiving an invitation, regardless of whether you accept it or not, remember to respond promptly. In the United States, this is a basic social etiquette.
3. Follow the instructions on the invitation, such as time and dress code. If there are no specific dress requirements, dress according to the occasion and type of event. Be aware that in many situations in the United States, you cannot enter without formal attire. It is very strict, regardless of who you are!
4. In public, do not blush when looking at beautiful women; blushing can sometimes indicate guilt. For example, at the beach, where many women are sunbathing, it is important to remain calm and natural, as that is healthy.
5. Do not act recklessly in bars or dance halls, as the reality here is not as chaotic as in movies. Without basic self-restraint, your uncivilized behavior will still be looked down upon by others.
6. Do not flirt with women casually in bars, as the ensuing situation may be difficult to handle. If you do not understand French or Spanish, you may awkwardly resort to drawing with friends to communicate. Also, do not have overly high hopes for romantic encounters, as the openness in the United States is not as imagined; women may blush when dancing with strangers.
7. At adult gatherings, children are usually not invited. Although the United States is a paradise for children, most adult gatherings do not welcome children. Therefore, young parents in the U.S. must arrange for babysitters in advance when attending social events. If the host says children are welcome, mothers should remind their children to behave politely while visiting someone else's home. Thus, children in the U.S. tend to be very well-mannered when visiting.
8. During gatherings, do not ask inappropriate questions. The United States places a high value on personal privacy, and Americans do not inquire about the personal finances of newly acquainted friends. Questions about religion, such as: "How much do you earn each month?" "Who is in your family? Where does your father work?" "How much did you buy this house for?" are considered intrusive.
9. Drink more tea and less coffee, run in the morning, and avoid becoming a "beer belly." Successful individuals in the U.S. are characterized by their balanced physiques. The foundation of success is the application of knowledge and respect for rules, not manipulation or indulgence.
10. Get used to waiting for red lights, even if no cars are passing. Ignoring red lights will result in immediate disdain from others, leaving you regretting your actions.
11. Here, municipal officials may seem unremarkable and not imposing; citizens encounter them with a casual attitude, even reluctant to shake hands.
12. Understand what learning is; human life is short, and you cannot experience all the wonderful things. Learning helps you organize the experiences you have not yet encountered. Those who understand learning will find their circle of friends expanding!
