Excerpt from a baker's dozen
david matherne

i ain't no valedictorian. i'll give you that. but i'm certainly not the loser my step-father johnnie likes to think i am, either. mr. oh-so-famous local johnnie pipehead of "johnnie on the spot plumbing."

in order to achieve more precise meaning, the initial sentences, "i ain't no valedictorian. i'll give you that." should be changed to
a) i am not the same person as the valedictorian.
b) i am jealous of the valedictorian, that is true.
c) i am upset that i did not receive the honor of being named 'valedictorian.'
d) i admit that i am not the smartest or most motivated student in the school.
