Living in the USA, I've noticed an interesting social dynamic—sometimes, American friends don't initiate greetings with people from other countries. From my experience, this isn't necessarily about rudeness but can stem from cultural differences and social habits. In the US, greetings can vary widely depending on the region, individual personality, and social context. Americans may be cautious about how they approach or acknowledge others, especially if they are unsure about cultural norms or fear unintentionally offending someone. This hesitation can be mistaken for ignoring or not wanting to engage. Another factor is that people often tend to connect first with those who share similar backgrounds or languages, which might make international newcomers feel overlooked. However, this is more about comfort zones than exclusion. Over time, as friendships develop, barriers tend to lessen. To improve interactions, it's helpful for newcomers to take the initiative in starting conversations or sharing aspects of their culture. Many Americans appreciate openness and friendliness and often respond positively when approached warmly. Understanding these subtleties can enhance personal relationships and ease cultural adaptation in the USA. Remember, building trust and friendship across cultures is a gradual process that benefits from patience, empathy, and mutual respect.
