Words that my three-year-old knows that I did not when I was six.
1) Sushi- This is number one. I knew about Chinese food, not Japanese. Of course in Utah no one that I knew of ate raw fish.
2) Cafe- Ok there were plenty of Cafes, at six I knew the word restaurant or Mc'Donalds. My daughters concept of cafe is very different from the one I had growing up. Cafes are where daddy gets lattes, which brings me to my next word.
3) Latte- I knew about coffee; to me it was something only Non-Mormons (bad people) drank. Lattes on the other hand were not something I knew anything about and I doubt that there was a single place in Utah( especially not Provo) in the mid seventies where one could be had. My six year old self would be utterly shocked that I partake of it.
4) cell phone- this one has less to do with culture and more to do with the advance of technology. I mean, my parents had no clue about PCs, VCRs etc.
I know there are many more words and concepts than this little list. I will re-post this when I hear them.
