It took me five years to graduate college, not four, and about this I feel a little insecure. Yesterday was my last day of work, at a job I have worked for almost four years, and my boss was asking me about my college experience. Eventually she asked me how long it took me to finish college. I think she caught me off guard with this question. I lied and told her it took me only four years.
I realize this is a harmless lie, but it is still a lie. I wanted to know what Christianity has to say about fixing a mistake. If you tell a small lie like this, are you obligated to go back to the people you lied to and tell them the truth? (This would be very hard and awkward for me to do, especially since my job just ended.) Or, in cases like this, is it enough to be repentant, and make a sincere effort to be more honest in the future?
