This made me laugh and I can fully understand where you are coming from and you bet there will be many more questions that you will have in September like... How much to spend on a birthday present, what about inviting friends home to play to your house, which may be smaller!!! All these things went through my mind too, so maybe don't change the name yet!
The reality is there are so many different characters and incomes, that it really doesn't matter. At our school, which we started at in September, there are children who walk and catch the local bus. Is there a school bus near you?, a lot of private schools have buses that go quite a way from the area the school is in, because the catchment area is so large.
In fact, unless you have a car park at school which parents drop off at, very often you won't know what people drive anyway, at our school the sideroads around the school are jammed with different vehicles.
The sterotype vehicle for someone who is a WAG, or WAG wannabe, is a large pristine white Range Rover or Overfinch (posh Range Rover) followed by a few Landrovers, lots of Audi 4x4 and Mercedes ML 4x4, however, they must be WHITE!!!!!! Then you get the trendies - Minis, Fiats, GTI's, there is one Aston - which I must admit is the only one that impresses me, because it is beautiful. The rest of the normal mums are driving anything, I will often use our messy old Saab estate, full of dog hair, wrappers etc. In fact it is such a mess that my otherhalfs work colleagues refuse to get in it if they have to move it in the car park!!! A friend, who I later found out is a very and I mean very wealthy estate owner, drives a really old Jeep 4x4, she hasn't got to prove anything to anyone!
Lots and lots of people walk into school and I wouldn't have a clue how they get there!
Oh and lots of friends, aunts and numerous grandparents, pick up and drop off, some parents I haven't met yet, as someone else brings/collects their child.
Make a few friends with the 'saner' down to earth parents and you will have no worries, you will spot the 'posers' a mile off!!!
