My mom use to have a boyfriend who Ennis reminds me off. They both talked a little 'ignorant.' And he used to say 'huh?' ALOT too. This guy was below the average intelligence, though I love Ennis, we know he isn't as well educated as he had liked to have been.
"Yer nineteen, you can do whatever you want now, huh?"-He meant, to say "when i was nineteen, i was wild, crazily horny, and screwing a beautiful man in a tent, smaller than the bathroom. Since I was all goofy, you can be to."
