I recently changed the spelling of Lexus to Lexis. The fact Lexus is a car name bothered me. Really, really bothered me.
Don't worry, I consulted Lex about this change and she shoved her Kong in my face. (We've determined that means she's happy with the new spelling.)
Not only is it a nicer looking word, it also works better for future "A Lexis on Fire" posts - when she earns a new title.
