I have been re-watching the series over the last few nights and been really struck by what crap parents Sue and Pete are. I know that's part of the joke, but they're really really bad.
Once Karen and Ben got past the cute curly headed moppet stage they were actually obnoxious kids. Rude, disobedient, constantly answering back, disliked by fellow pupils and teachers. Karen even had to be called in by her Headmistress during her first year in secondary school for a conversation about how dislikeable and annoying she is.
AIBU to think Sue and Pete were useless parents who should have done a bit more telling off and a bit less 'reasoning' with their kids?
