Meaning: I’m not naïve or stupid. Use examples.
Rewrite 1: I didn’t leave my brain at home
Rewrite 2: I’m not fresh out of hick high school
Rewrite 3: I didn’t just graduate from kindergarten
Rewrite 4: I did pass15 the class in simple smarts
Rewrite 5: I’m not a Little Red Riding Hood in the forest
