couple of years ago we had some girls stay with us, daughters of friends of ours ,18 and 16
While they were here, I let them use the charger
Well, one snowy, freezing winters day they go to meet someone, but instead of pulling left out of my drive, they turned right and got lost
Luckily for them, they ran out of gas before they got too far lost
It was also that day, they learned the lesson of keeping a cell phone at least partly charged
