Illeism or sillyism
Who would have thought that it might be good to talk about yourself in the third person? As if you weren’t you, but him? As if you weren’t actually there, and anyway, you didn’t want yourself to find out you were talking about him in case it seemed like, well, gossip? I mean, only royalty, or the personality-disordered, are able to talk like that without somebody phoning the police.
