When I started to understand that some people lived different lives! When did you know and what opened your eyes?

Born into a "respectable" working class family (my parents description) in the late 40's, I never went hungry, always had shoes that fitted and although sometimes cold, was never worried about anything really. I was just like everyone around me. My junior school was good and I thrived. I didn't really understand that my parents lived a pretty week by week existence until I went to a secondary school that was actually the preserve of the middle classes. It wasn't the big houses that they lived in, or the car in the drive it was the pantry! I wass reminded of this today today when I looked at how much food I have in mine. A freezer full of meat and other bits and bobs, cupboards full of jars and tins, we could live for several weeks without buying anything. I remember my parent's pantry, it had a tin of salmon, a jar of Fussells cream, a tin of mandarin oranges and a little tin for the shillings for the meter. I remember visiting the home of a school friend and being completely overwhelmed by what was in their pantry, it was full of stuff I'd never seen and certainly never eaten. Anyone else have memories like this?
