Damon says the funniest things

I was studying with Devon going over his spelling words the other day. Damon was across the table having his after school snack. Devon says "This is hard and I can't do it, I just can't do it" with frustration and almost tears. Then you hear Damon say "You just have to believe in yourself Devon" of course I laughed and said thank you to Damon but Devon didn't find it to amusing.
