I'm not totally convinced by this Fatigue stuff. It would explain the tired and achy. But? A sudden desire to knit socks while listening to The Navy Lark. It's either a cry for help or she's possessed. Possessed by an 85 year old woman. That's my guess.
I'm keeping a close eye. I've put all my own work to one side. The first hint of a spam fritter or an interest in Arthur Askey and I'll spring into action.
