What is what does it mean when someone calls you by your first and last name?

When someone calls you by your first and last name, it may indicate a level of formality or distance in the relationship. It may be a way of showing respect or conveying a sense of authority. In some cases, it may also be a way of differentiating you from others who may have the same first name. However, it can also depend on the tone and context of the conversation and the individual's cultural background or personal upbringing.
