I really should have known better. I checked up on Cathie, who seems much better, then went down to file my income tax. Apart from the usual cold symptoms, I felt fine. Got back into the house and fell asleep - something I never do during the day - and woke up about four hours later aching and sweating. The flu has made its return. Rather than bore you with how bad I'm feeling (I guess I'm not the first, and that I won't be the last to get flu), I'm just going to sign off and head up to bed in the hope that I'm better tomorrow.
At least I got my tax done!
