Whoops!

We are in the process of having a new patio and have been talking about whether or not we should get rid of part of this wall. We decided to keep it, but then maybe it doesn't want to prop up the edge of the patio any more?
I had bought an armoire from the Brocante today, and drove round to the kitchen door to deliver it as near as possible without too much lifting. I had some friends to help me and all went well until I just touched the wall as I drove off.
I didn't see the wall which has been standing there forever, the sun was in my eyes, the wall fell over just as I drove past; I've yet to chose an excuse before Mr Frenchtoast finds out! Oh and the car is a bit scratched too!
