alright guys i just started a blog where i make my essays (not my school essays unless i'd find them something i'd want to post here), and started by copy pasting my essay about the dictionary into a blog entry
Turns out my ancestor was a bit upset about the whole language fragmentation issue, like Soda and Pop... Ask for a pop here in Florida people will look at you funny. Ask for a pop up north and people know what you want lol
