When someone hides an item owned by someone else it may not be considered theft in certain jurisdictions such that when the owner catches that person and calls that person a thief the comment is considered a personal attack. In other places where depriving the rightful owner of his rightful entitlement and enjoyment of his possession is considered theft and the thief is caught and called a thief it is not considered a personal attack but rather a statement of fact. See: To call a spade a spade.
