“Camping Dishes”
Probably a weird example, but, growing up all of our dishes were made of Fine China, Waterford glassware, etc. And I just thought that’s what plates and stuff were made of because we didn’t have anything else. Then one time, I went to a friend’s house for dinner, and we ate on colored plastic plates and non-matching plastic cups. I just thought that was the weirdest thing ever and asked why we were eating with “camping dishes.”
