My family hails from England. My great grandfather had some quirks, that have passed from him to my grandfather, and then to my mother and me.
My family always seemed to pay way more attention to greetings, manners, and table etiquette than my friend's families, lol. My mom said it was because of my Great grandfather and his British heritage. (?) We were expected at a young age to be well mannered and have excellent table manners. My grandfather would smack the back of your hand with his knife if you were acting up. We had to know all the different utensils, and what they could be used for - as in the seafood, cake, fish, dessert forks, knives, glasses, etc. Dinner was always formal, and you couldn't eat until after my grandfather started eating.
We used different nicknames too... It was love, or lovie, and occasionally duck/duckie as endearments. Not sure where duck came from. DH actually calls me lovie most of the time.
I think a lot of my family food quirks have come down the line from our British family... tea (no coffee here), crumpets, kippers, Yorkshire Pudding, roast potatoes (I didn't have mashed potatoes growing up, lol), Brussels Sprouts. I don't know if the last are really British, but I've grown up with them.... and most other people didn't like them, or didn't have them served at meals.
This is just my family... I'm not totally sure if this is because of my great grandfather, I've just been told it was like that because of his heritage.
