During interpersonal, you get to see the whole-ness of the conversation because it is one-on-one. The two people, especially if they are giving their full attention on each other, will be able to know the accent, tone, language, etc. of the conversation. And since the distance is not that far, they would be able to see their non-verbal cues, such as rolling of eyes, fidgeting of nervous, crossing of arms signaling close-mindedness, etc.
