In the novel "The Crossover", Ode to My Hair"

If my hair were a tree
I’d climb it.
I’d kneel down beneath
and enshrine it.
I’d treat it like gold
and then mine it.
Each day before school
I unwind it.
And right before games
I entwine it.
These locks on my head,
I designed it.
And one last thing if
you don’t mind it:
That bet you just made?
I DECLINE IT.
