No i18n for this error message, since it should never happen.
He was riding his bike through town and went into a store, came back out and saw that his bike had been stolen. His mom had to come pick him up, but by the time she arrived, he realized that he had just forgotten what his bike looked like and it hadn't been stolen after all. A week later, his bike was actually stolen. He has a bike lock, he just didn't think it was necessary.
