What are the pros and cons of passing notes as opposed to in-person conversations?

In fact, writing notes is just a way for students to communicate with each other, which is easier than whispering to each other in class. More importantly, it is an emotional exchange. When you talk in person, you are usually brief and concise, and you don't feel your feelings and expectations. So compared to that, passing notes is favorable. But it is that passing notes in class is more disadvantageous than advantageous. Compared to both, writing notes is better.
