base on my opinion, maybe it is not all about them to be the star or what we so called want attention, they may be talk about themselves in a way that they just want to share what is good and bad they have encountered, sometimes we need such those person sharing their experience good and bad so will be able to avoid whatever we need to avoid, learn a lesson to what they have learned. I hope you got i what i mean. i am just happy reading some of their post.
