We have two who got the bill in the dc's school. The fathers have big jobs in the city, one of the mums is a sahm the other works very part time.
Always busy doing something impressive with their kids, hiking, sea swimming, skiing at half term etc..
Their dc are very bright & they seemed to have chosen their extracurriculars wisely with a view towards the red bricks & one child wants to apply to an American ivy for a scholarship in her chosen sport (rowing)
They just seem so clued in & have know how or inside knowledge! Beautiful, huge, spotless houses too. Hosted coffee mornings for the PTA.
Would love a life like that! DH says it's simply down to money but it's more imo.. Their kids are also much more confident & eloquent than mine!
