I work in a completely different field to business, but I have done years of training and postgraduate training. My job is stressful and a LOT of responsibility. People always want to pick my brains, or make conversation as I put it, wherever I am -parties, school run etc etc. I wouldn’t dream of saying something like this! I would never behave in such an arrogant way. She really shows her immaturity with posts like this. She’s totally unqualified to lecture others on a subject she’s never had experience in other than a few seminars and books read!
