Mystery of Boy's Hair - Solved!

So I was washing Boy's hair - miracle enough that he was letting me - and I told him that he had very thick hair, which he does, and I was acting like that was a good thing, although it's mostly because he hates haircuts so at this point he looks a bit like he's wearing a mop. Anyway, he explained that his hair was thick because he had so many friends - and that he was stealing their hair for his own.
