Last night, our kid's cousins' cousin (YOU figure that out!) Isobelle had a sleepover at our house, because her little brother was in hospital with jaundice. He should be OK today.
Of course, having Izza over is a pleasure, but it also means that our boys go slightly nutty. So the whole household volume went up 3dB (which is to say twice as loud!)
And trying to stay focussed on the family routine was a challenge!
Keon, of course, turned up HIS volume in compensation for the lack of attention.... another 3dB.
I reckon that if you could harness sound energy, we could put power back ON to the power grid!
Oh, well...
