I am reading Sadie by Courtney Summers. There is this sentence that I do not understand.
I want to live my life on the internet. Everything is perfect there. I found Kendall Baker on a computer in a library in some forgettable town along the way. She's beautiful. A girl with a glow. Eighteen years old, but the kind of eighteen they write about in books. The kind of eighteen that lives faster than the speed of hurt.
What does the author mean by speed of hurt here?
