there is a difference between bragging, or admitting for two reasons. If asked point blank, do you lie? and if you lie what is the impact on the trust. Secondly it is a way for others to realize that an individual can change and that is it never too late to make a change for the better. Some people just stay stuck in wrong choices because they think that now its too late, that change will not get them forgiveness or change will never be that they turn a new leaf and move on forward with a better lifestyle.
