I know your comment wasn't directed to me, and I only speak for myself, it wasn't what she said since that, as always, was brilliant, it's the pitch of her voice. Some of us females have a harsh, scratchy, piercing sound to our voices when we get excited. I'm sure she's aware of this, but for whatever reason perhaps chooses not to address it.
Maybe she hasn’t ‘addressed’ this because she prefers to be exactly who she is.
Honestly, as a woman I am just amazed that any woman could comment on her voice, it’s so surface it makes me wonder if you even hear the message.
Keep doing what your doing Sarah, being YOURSELF is the greatest gift one can give to this thing called life!!
