If you’ve never been to a Big Lots store, you need to. It’s a lot like a dollar store, only they have a wide variety of stuff you won’t find elsewhere. Like Belgium Cookies.
My sister and her family live in Belgium. You can’t buy Belgium Cookies there. Which reminded me of when we lived in England. “English muffins” were not to be found. “Muffins?” Yes. (Same phenomenon.)
What is an “inside/outside” term that you’ve experienced?
