The phrase "I will talk to you in person" means that the person intends to have a conversation with you face-to-face, rather than through written messages, phone calls, or other forms of communication.
When someone says they will talk to you in person, it suggests that the matter they want to discuss is important, sensitive, or requires a more personal and direct form of communication. In-person conversations allow for better clarity, emotional connection, and the opportunity to read nonverbal cues, such as body language and facial expressions.
Sometimes, people may choose to discuss certain topics in person to ensure privacy or because they believe that it's more appropriate to address the matter face-to-face. Additionally, some conversations are simply better suited for in-person interaction to avoid misunderstandings or to convey emotions more effectively.
Overall, when someone tells you they will talk to you in person, it indicates that they value the importance of the conversation and prefer to have it in a direct and personal manner.
