Which point of view does the narrator use in the passage?

"Hi, Mr. Tushman, it's so nice to see you again," said Mom. "This is my son, August."
Mr. Tushman looked right at me and smiled and nodded. He put his hand out for me to shake.
"Hi, August," he said, totally normally. "It's a pleasure to meet you."
"Hi," I mumbled, dropping my hand into his hand while I looked down at his feet. He was wearing red Adidas.
