I have been instructed to eat hard candy (lollipops, candy canes, etc.) because I lost my voice and eating hard candy helps. Yep.
And I was going to help my World Geography teacher do a video where all I had to do was read a line off something, but I lost my voice and finally halfway convinced my friend to go and take my place. Lucky for her, my teacher's phone wasn't able to transfer videos, so she got out of it.
