It's human nature for many people to enjoy talking about themselves to friends and acquaintances. If something is going on in their lives, lots of folks like to talk about it to others. And that's fine. There is nothing wrong with that. However, a small percentage of people I know constantly talk about themselves, and never ask how you're doing or what's going on, positive or negative, in your life. It's like they don't see that nobody wants to talk to folks who only talk about themselves and clearly don't even try to pretend like they have in interest in the lives of you and me. If you like to talk about yourself to others, that's not bad in of itself. But, for goodness sake, ask others about how they're doing, even if you care less!
