Why does Shawn get a little pleasure out of his dads poem in Stuck in Neutral?

On the face of it, you'd wonder why on earth Shawn would derive any pleasure from his dad's poem. After all, it concerns the difficulties and challenges that Shawn's old man has had to overcome in dealing with his son's condition. Shawn's convinced that his father wants to kill him, to put him out of his misery, to use that ghastly expression. And the poem, however beautiful or skillfully recited, appears to confirm his suspicions.
Yet Shawn is impressed by his dad's poem all the same. Or rather he's impressed by the reception it receives when his dad recites it. All of a sudden, everyone's talking about Shawn, and he loves being the center of attention. This feeling of pleasure will only grow when his dad's poem goes on to win the Pulitzer Prize.
