Seita Personality Type, MBTI

Seita personality type is ISFP, since they are so quiet and reserved. And so I had a lot of trouble trying to figure out how to communicate with Seita. Because even when I tried to get him to talk about himself, he would just say that he was sorry, or that he didn't have the words, or that he didn't have the words to express how he felt. This is a personality type that does not want to talk a lot. They just want to be left alone. That was a difficult thing for me to understand. But when I finally understood it, it made me realize something else. He wanted to talk, but he didn't know what to say. He was afraid of saying the wrong thing. Or he would begin to talk, and then he would hesitate and stop, and then he would start again and stop again. He was like a person who is trying to put two and two together, but they're not sure if they're getting it right. Even in his own head he wasn't sure if what he was saying made sense.
