Benjamin is a young man from the early 2012s. He's about 19 / 20 years old and is the main protagonist of the story. There is a bit of time travel, so he will also need to sound middle-aged (in his early 40s). He is Mexican-American and is from Philadelphia. 

As protagonist, he initially starts off with a mildly-optimistic but otherwise tired personality due to decisions about college and his next steps in life. When the story starts to progress, he becomes a little more jaded, and wary of the world before finally circling back to becoming amiable and enthusiastic about life.
