Obviously, people have different opinions about this topic. I really do enjoy hearing about other people’s life stories and experiences–successful or otherwise–whether related to family, helping others, exciting educational or career accomplishments, sports quests, travel or anything else.
Our family and friends are very open, warm people who support each other in every way we can. We’re all very happy with our lives, so we might tend to “overshare.” To each his/her own, but lying (per the OP) is definitely where I would draw the line.
