Hmm I don't see anything wrong with it, we all act a little stupid when we're by ourselves, this girl just happened to upload her alone time silliness on Youtube. Really I don't think she deserves to be labeled a freak or whatever, we don't know her personally and labeling someone on just a silly little video is just as immature as what this girl did. Nothing wrong with calling the vid stupid, but no need to call the creator any names.
I totally agree with you..
I agree too. Also, I don't think she sounds like she's 17. She probably had to put that she was 16 or something when she initially signed up for a YouTube account, but she sounds
quite a bit younger. And, I will be the first to admit that I used to make my own "radio shows" complete with singing and "interviews" when I was between the ages of 8-12 or so. They are fantastically embarrassing.
So, let the girl be. We've all done weird things before.
