Don't waste your time warning flies
Q: After swatting flies, is it best to clean up their corpses or leave them as a warning to their brethren?
A: Flies lack the mental capability to know what a "warning" is. You may note that if you repeatedly swat at, threaten but never injure a particular fly, it will still happily dart for your food despite the repeated "warning". Consider that they can't even do this, and that recognising a corpse as a warning is a whole another level of intelligence.
Sleepover peril
"During school holidays there is often a reciprocal childcare deal that goes on between parents [well, mostly mothers]. A 'you have my kid for a sleepover and I'll have yours' kinda thing," writes Suzanne. "Well this was my first and last. I agreed to the sleepover for my 5-year-old boy and even though I was coming down with something I stuck to the plan. It all went well until the following morning. By the time I dragged myself out of bed, this is the scene that greeted me in the kitchen ... The smaller of the boys was standing on a dining room chair in front of the toaster with a too-hot piece of toast retrieved [skewered on a fork] and the other boy [mine] was also in the kitchen standing in front of a piece of firewood, with a hatchet above his head, ready to swing. FREEZE! They were a bit cold and hungry, they said. A serious talk about domestic safety followed, but I chose not to tell the boy's mother."
