Then the shock wears off a little and you have (in my case) two perfectly formed little human beings, wide-eyed, innocent in the ways of the world and thirsty for knowledge like a parent is thirsty for wine on a Friday night.
This is where the mischief creeps in.
How is honey made? They innocently ask and you explain about bees and hives and beeswax and the miracle of nectar and pollen and they are fascinated, but they don't believe you because, really, it's totally ridiculous. But then you take them to Newquay Honey Farm and Prove It. Ah ha!
Chutney, of course, is made by earwigs. They absorb this fact. 'Earwigs' is a great word, as is 'chutney' and the juxtaposition of them in a sentance is pure joy (and something we must be thankful to Eddie Izzard for).
From then on every time you find an earwig in the garden it's: "Oooh look! It's going shopping for chutney ingredients."
Wasps, by the way, make jam. This is a logical thing because you often encounter wasps in jam jars or in those wasp catching pots which are baited with jam and are known in our house as "jam factories".
I didn't think I could expand on those two, but tonight I was handed a perfect opportunity by R6.
"Mummy," she said, "how is yoghurt made?"
"Well," I said, thinking quickly. "To get yoghurt the cows do special yoga which makes the milk thick and then you get yoghurt."
Bovine yoga --> yoghurt. Simples.
Again this has logic in the animal kingdom because Mido the dog does yoga before he eats his breakfast. He gets out of his bed, does Up Dog, Down Dog, says 'woof' and then eats. So it's not such a huge leap from the dog doing yoga to cows doing yoga.
I'm going to get into such trouble one day. Oops.
