When I was a child...
having a car
a colour telly
a house phone
branded anything
Central heating
not sharing bathwater with siblings
not having itchy old army blankets on the bed to keep warm in winter and a hot water bottle
having biscuits freely available and not rationed
having a whole chocolate bar to yourself rather than shared with the family
eating out
a takeaway that wasn't fish and chips
eating a meal called supper
eating soup or any other starter before a main
food shopping in M&S
being able to choose your own new clothes in shops instead of getting ill-fitting unchosen hand-me-downs
having any tradespeople in, instead of doing your own decorating, cleaning, renovating, etc.
a sodastream
having a tutor
having a cleaner, gardener, handyman
I realise now that even when I was a child, most of these things were just middle class, not posh. But at the time, middle class was posh to me.
