I have one coworker, unfortunately next door to me at school, who is the Queen of trivial conversation...and specifically ALL about herself, her family, her what's for dinner, blah, blah, blah. As soon as I try to interject anything into the conversation, she waits impatiently till she can return to her subject...Herself! I have a few other acquaintances like this...do not consider them friends. Such people are incapable of being friends to anyone.
I like a conversation in which there is genuine interest and give and take. Not too hard to find, really.
