Anyone noticed how we also tend to have different half-lives for labels describing people, e.g. someone who murders or rapes someone never loses the 'murderer' or 'rapist' label, however someone who stole something irrespective of its value or lied about something - material or not, do not tend to think of themselves as liars or thieves for as long as they are certain they got away with it or others have 'forgotten' it, or rationalized it away? Wonder why....
