Paul let's his friend DJ borrow his truck to run a few errands which should only take about an hour. Five hours later, DJ has not returned with the truck and has stopped answering his phone. The following day, DJ has still not returned the truck, so Paul calls the police. In this instance where DJ was allowed to borrow the truck, but has apparently formed the intent to permanently deprive Paul of his truck after it was taken, what term best describes this scenario?
