In The Absolutely True Diary of a Part-Time Indian by Sherman Alexie, what is Mr P described as?

In The Absolutely True Diary of a Part-Time Indian, Junior's first description of Mr. P is vastly different than the one that follows.

When Junior first sees Mr P, the geometry teacher is described as a "weird-looking dude."  The cartoon Junior renders shows Mr. P in visual details that would match such a description.  Mr. P stands about four feet tall, and is "bald" but with "dandruff."  The food stains on his clothing are...

In The Absolutely True Diary of a Part-Time Indian, Junior's first description of Mr. P is vastly different than the one that follows.

When Junior first sees Mr P, the geometry teacher is described as a "weird-looking dude."  The cartoon Junior renders shows Mr. P in visual details that would match such a description.  Mr. P stands about four feet tall, and is "bald" but with "dandruff."  The food stains on his clothing are only matched in awkwardness by Junior's descriptions of him as sometimes wearing pajamas.  Junior describes him as a "weird old coot."  Finally, Junior makes it clear that he sees Mr. P as a "lonely old man who used to be a lonely young man."  

After Junior's display of anger towards Mr. P, there is greater complexity as to what Mr. P is described as.   In the course of their conversation, Junior begins to see Mr. P as a source of inspiration.  Mr. P reminds Junior of his talents.  He recalls the talent of Junior's sister.  Then, he brings out Junior's own past in terms of fighting through seizures and physical challenges.  Mr. P is able to inspire Junior to think about leaving "the rez:"  "Son,... You're going to find more and more hope the farther and farther you walk away from this sad, sad, sad reservation."  Prior to this moment, Junior never envisioned life beyond the reservation.  However, Mr. P teaches Junior the power of hope and the value of believing that people deserve more. Mr. P reminds Junior that he is a "bright and shining star." This triggers a change in Junior.

While initially described as a "weird-looking dude," Junior ends up describing Mr. P as a transformative force of change.  Mr. P is instrumental in altering the way Junior views himself, his world, and his place in it.
