There's no one answer to this question - it depends on the situation and what works best for the speakers involved. In general, though, facing each other can help with communication by providing visual cues and body language that can supplement or clarify what's being said verbally. Additionally, eye contact can help build rapport and trust between speakers. That said, there are also times when it might be better for speakers not to face each other directly. For example, if someone is feeling shy or uncomfortable, they may prefer to have their body turned away from the person they're talking to. Ultimately, it's up to the individual speakers to decide what position feels most natural and effective for them.
