People who talk about themselves all the time
(this is a repost from Gransnet)
I know one or two people like this. No matter what the topic of conversation they turn it back to themselves and their concerns the whole time. Do people who do this have some kind of compulsion or disorder or are the just hugely lacking in awareness.
In general, the people I know who do this are quite kind beneath it all but just frustrating in their determination to bring things back to themselves all the time.
