The granny came with the car.Yes, the granny is yours, delivered with the car. Correct? The very few times I publicly charged it almost always worked, actually I have a very hard time remembering it did not. Except of course for when the charger was out of order. That obviously did not work, I even did not try.
There's a story about grannies in france I learned about whilst at uni by a lecturer researching silly/mythical stories...
A family of 4 went camping on holiday to France with grandma. Sadly at the campsite grandma died. The kids were too young to leave behind so they decamped, packed the car up. Couldn't sit a dead grandma in the back with the kids. So wrapped her up in the tent and put her and the tent on the roof rack. They drove into the village and went into the gendarmerie. Reported the death and came out with the officer.
Only to find the car, with grandma wrapped up on the roof, all stolen.
