  • Not fare

    • What’s not “fare”? Mark Rober doing something for someone who has a life threatening illness who might not wake up tomorrow? While you’re waking up, saying stuff isn’t “fare” (correct spelling is fair by the way) knowing you’ll be alive when Fletcher doesn’t know whether he will survive to adulthood? You disgust me.

  • Also I'm planning to be a NASA engineer because I know alot about space plus you are one of my favourite MRlevelrs ❤

    • I hope you get to be an engineer one day 😊

  • Mark rober i also have autism plus I know how many molecules it takes to form a human body how many months it takes for a snake to shed there skin
