It's the way Sophie tries to explain something intellectual that annoys me, it always sounds like she has just been told the explanation and she is trying to inform us through Pete, I just don't like her and never have , I lumbered Pete in with my dislike but he actually does say some funny things , and then as you say Sophies annoying laugh starts , I wouldn't mind them replacing Sophie for Petes new wife , I think he is getting married , obviously it would be up to her but it would be better than Sophie imo
