Well the brickies came back this morning to clean up the broken wall. Appears a wallet was left at our metre box. On Tuesday we had seen a car parked on our block using our power but didnt report in case of vandalism!!!!!!!! So today we find a wallet, look at where the car was parked and work out the high liklihood of the back of this car ( a station wagon) clipping the wall and causing a domino effect. The inner walls are not yet built so there was only minimal bracing.
To cut a long story short, our little friend was back tonight to use our power and i took the liberty to phone the police this time. He was shifted on with a a very very stern warning!
I suppose I feel great relief. We have a plausible explanation for the collapse of a wall, the old bricks cleared to start again on Monday, another brickie team assisting, no damage to my beloved polished concrete slab and the show back on the road.
Thank you to you all for your support!
