Summary
Analysis
Mateo tells the reader that 12 hours ago, he received the call saying he’s going to die. He’s said lots of goodbyes since then, none more important than the one he said to Past Mateo. Past Mateo stayed home when Rufus took the current Mateo out into the world. The boys are here together, and Mateo wants to help Rufus in any way he can. Mateo feels more alive than ever.
Having said goodbye to his mom, Mateo can now turn his attention to helping Rufus achieve his own sense of closure. As Mateo comes alive and comes to terms with his decisions, he chooses to take the words on his headstone to heart: he’s going to live for Rufus now.
