Noah did not even finish high school. (Not that he wasn't capable, circumstances just did not allow.) It is possibly something he is hesitant to tell Joy that. College never even crossed his mind since... in his mind, what is the use of a degree in the woods

Noah did drugs once. On accident. He didn't examine the mushroom close enough. Never again any drug, not that he would have purposefully done so anyway

And yes, he ageees that Joy is awesome and perfect and that she does have a peeky ass.
