Can't remember where that phrase originated - I know it was from childhood, and I think it was one of my grandma's. It describes well how I am feeling. I've got a really heavy cold and have given in and taken the day off, with much guilt. I even called the cover supervisor to see if they could manage if I didn't come in. However, the fact that I was more able to face setting work than going in indicates that I need to be at home - that, and the fact taht my voice is definitely on its last legs.
Really feeling grim - shivery and snuffly, coughing and hacking. Here's hoping the weekend provides enough time to recover. Bleh.
