Precisely this. And this is why she is the laughing stock of the school gate. There are some mega wealthy families at DD's school. I mean, billionaires. But they are ultra discreet. They would actually be horrified if anyone knew about their wealth, to be honest.
Interestingly, my friend (whose kids go to Thomas's Battersea with Prince George et al) says that Kate is the most humble, low key mother. She does drop off mostly in activewear (not the fancy kind). Make-up free, quite often. I also have a friend who is the daughter of a Duke, but you would NEVER know it (the only reason I do is because I've known her since university and met her dad once and was shocked when I realised who he was). Wealthy, classy people downplay everything and feel horrified at the thought of rubbing it in everyone's faces. Our Laura, on the other hand, is just the opposite. A complete arriviste, trying to prove herself by flaunting her cash. It's so brash and very unlikeable I'm not surprised she's considering moving, to be honest, as she has been so ostracised by the other mothers, who literally gossip about her behind her back constantly - she must be aware that she has made a fool of herself in the school circle, at least.
Also...white leggings with 4 kids under 5. Come the f+++ on...
