It was confusing for me, because my entire extended family is rich and my mum was rich, but when my parents divorced after my dad bankrupted us, we had nothing. So i had a posh manners, posh voice, and my mum had some really nice furniture, some of which se sold, but the majority of my wadrobe is second hand, this year at christmas i was freaked out by the amount of stuff we had because of an inheritance when a relative died. I've never been on holiday with my family, our stuff like microwaves and washers always break because they are the cheapest thing availible.
We are not so bad now, but when i was a kid we lived of spaghetti bolognase and whatever was cheap, i couldnt go to friends houses because of petrol money and i owned three pairs of shoes, school shoes, pe trainers and home trainers. They got replaced once a year.
