Tomorrow's COMMA CLUE is going to be about subordinate clause openers...so I'll leave you with this little jingle to sing to yourself if you have insomnia tonight (instead of counting sheep!):
When you start a sentence with a subordinate clause,
Put the comma in when you hear the pause!
And then my sweet middle school students, knowing my love for the ballroom, all rise up from their seats and shout "CHA CHA" at the end of it...I have the greatest students! :)
