I thought the myth for shaving creating darker thicker coarser hair was long gone. It only seems coarser because you're chopping off the hair mid way instead of letting it grow out to the natural end of hair. It certainly doesn't give you more hair follicles to shave, so it's not thicker. And it only seems darker when you first shave because you're noticing the replacement hairs change as you go through puberty.
I also thought at first that this might be something Leah wants to keep to herself instead of have on TV, but then again so many kids these days think it's fine to put their life on show for others. Additionally, I wonder if kids she hangs with have been talking about the hair on their legs which is a reason Leah is self conscious of having hers, but because the kids have spoken about as well as having talked about shaving already she's not self conscious about it. I've noticed that there are puberty related things that were still taboo when I was a kid that just don't seem to be as much of a taboo to talk about these days, plus are spoken about in more public ways and in mixed company.
Does Dakota have a job in Austin? I know he gets disabililty from the military. What is keeping him there, instead of KY where the rest of his family seems to be?
