Beginners effort Stewart.

My late father got into his brand new car parked on the drive after shutting up the garage. Hid first auto, lput it into reverse gear,, twisted a bit to look over his shoulder and applied accelerator. The car lept forwards, there was a loud crash and we found him sat in his car on his garage but on top of the garage doors
My wife reversed her own car out of the garage and was so busy telling me to do something whilst she was out that she reversed into the family car. It was of course entirely my fault made worse by hysterical laughter
You have my sympathy.
