Answer:
One of the reasons I grew my hair long last year was that I like how my bangs cover my eyes: it helps me block out the things I don't want to see.
Step-by-step explanation:
The sentence from R. J. Palacio's Wonder that contains an example of direct characterization is "One of the reasons I grew my hair long last year was that I like how my bangs cover my eyes: it helps me block out the things I don't want to see."
In direct characterization, the character is described in a straightforward and direct way. The physical description, what the person does and pursuits are described in direct characterization.
From the above answer, we see that the character has long hair and shys away from people she doesn't want to see.
