I think quite a lot of mine probably came down to not having a lot of money growing up...
Very rarely ate out - Aunty & Uncle might take us to Maccas if they took us shopping. Think I was 16 when I had my first Chinese takeaway with my boyfriend's family, I was asked what I'd like ... I've no idea?!
Pizza was cheese and tomato (like these www.tesco.com/groceries/en-GB/products/288442525 ) Finding out you could have extra toppings was a revelation!!
We didn't have snacks in the house.
Pudding was a Sunday only thing, and not every week. I find it strange now, that DH will want something sweet almost immediately after finishing his dinner.
A slice of bread and butter with our meals - probably to help fill us up.
I also can't remember drinking much as a child? We would have a glass of water with our school meal, and maybe a glass of fruit squash at home. Maybe that was just because the importance of being hydrated wasn't a big thing then?
I used to have constant headaches when I was younger, I probably just needed a drink!!
If we were visiting anyone - " you only speak when you're spoken to" I don't like social situations if I don't know people, because I find it hard to start conversations. I'll wait for them to come up to me.
