If you cook stuffed marrows on a Thursday, before Rainbows, and then leave them in the oven to keep them away from the cats, it is possibly better to remember that you have done so on Thursday evening, not when you open the oven again on Monday. I did wonder where the flies were coming from - but thought they were just after the cat food.
On a similar note, if you pick the windfall apples to stew, it is better to cut out the bad bits and discard more or less immediately. Leaving them in a jug for two days provides another breeding ground for the flies.
On a completely different note, if you are at Guides when the babysitter rings to let you know your daughter is entering minute six of a tonic clonic seizure, the one minute dash back home again quite possibly provides a similar cardio-vascular workout to a full session at the gym.
I'm just saying...
oh - and Mog is fine now, had more or less stopped by the time I got home and is sleeping off the rescue meds nicely.
