Well, doing a direct comparison to how I grew up, I'd have thought you were rich beyond my wildest dreams because;
You own a house (although with house prices as they are, that one has applied since childhood and all the way through adulthood so far)
You have carpet on your stairs
You're redecorating
You have carpet that probably goes all the way to the wall in each room
You have curtains and curtain poles or blinds, rather than thin bits of fabric not quite meeting in the middle on a piece of wire
You have lampshades/light fittings rather than bare bulbs
It's likely to be doubleglazed and have heating
You probably have one or two cars
Your child has his own room (and maybe you even have a spare room?)
It's clean. Because I'd been told that houses are only clean when people are rich enough to afford a cleaner.
You had food and drink available for the children
Your garden probably looks like a garden rather than the remains of an air raid shelter (at the time, 35-40 years after the end of WWII) and some cracked concrete
I think you might be feeling weird because you're not actually that poor kid anymore - to somebody else's child, you're the rich one - and that's a strange feeling when you realise that actually, you aren't doing that bad after all.
