Maintaining friendships across borders can pose several challenges, including differences in time zones, language barriers, cultural misunderstandings, and limited face-to-face interaction. Time zone differences may make it difficult to coordinate communication and find mutually convenient times to connect. Language barriers may hinder effective communication and require extra effort to overcome. Cultural misunderstandings can arise due to differences in norms, values, and communication styles, requiring patience and empathy to resolve. Limited face-to-face interaction may make it challenging to develop and sustain deep connections, necessitating creative ways to stay connected and engaged.
