The strangest thing happened on Thursday - out of the blue (I haven't been ill), I started to go croaky, then my vocal range got narrower, and narrower, until... I had no voice left at al. AT ALL!!
One of my students is deaf and can lip-read, so that was great - he was helping others to understand me, but it has been mostly frustrating. It's creeping back today though - yey!
I've been trying to whisper at people and writing notes over the weekend, and guess what happens when you do that? People actually whisper/write back! (If you don't believe me, try it.)
