What is wrong with being right? Nothing. Everyone, at some point, has gone out of their way to prove their point that they were right. Phil definitely should have apologised and so should have the kids who were being pretty cocky and loudmouthy. Gloria is forever trying to prove she's right and so too are some of the others. Point being - why was everyone so annoyed and also surprised that Claire had gone to so much trouble to prove Phil was wrong? Everyone and I mean everyone was just staring at her instead of maybe a few of them - especially Luke - should have said "good one mum" or "wow, that's impressive!"
Sorry but I did not like the way it was written about Claire - I didn't find it funny, only belittling.
