I think we've all been in situations where we are sitting in a room and someone is talking and won't let any others get a word in. The conversation switches and someone has the chance to talk and that same person shoves back in, changes the subject to revolve around them, and bam! No one can get a word in otherwise. What do you do in situations like this? Some talk over the person and butt their self in, while others sit quietly, stuck in a hell that is the other persons heaven. they are attention seekers. Has to, must be, loves to be the center of everything. You sit there and let the person have their own conversation party with themself. While you sit there pretending to be interested, laughing when cued, and nodding in appropriate spots. You try to look interested, oh wait, they are too involved with their conversation to notice.
