Okay, this is really lame, but I couldn't think of anything for X. I'm anxious to see what others did for this most challenging of letters (and I thought L was lackluster :)
Xavier is the only street in my zip code that starts with the letter X. I found that interesting trivia :)
I also worked for a doctor one time that had two middle names and one of them was Xavier.
X is a hard letter. Do you have a favorite X word?
In the meantime, have a great weekend!
