These people talk too much. They talk too much about themselves and do not listen to others. When other people talk, they often ignore it and change the subject about something they want to talk about. They are too focussed on what they have to say, how they feel then to be concerned with other's people emotions or ideas. They are often insensitive and cannot read body language. They will keep talking even if one has gtheir back turned away.
Although always listening isn't seductive, always talking when other people don't want them to talk is annoying.
