Secret Niece/Auntie Language

Picture of the Day for 3/15/2014. Today is my niece Michelle's birthday. (And my friend Suzanne's birthday as well!) A few years ago I accidentally texted Michelle some gibberish and she didn't miss a beat and responded in kind. It's become a running gag that we'll text each other random letters and symbols out of the blue. Since she's my niece and I'm her auntie and we're both named Michelle, we ALWAYS know what the other person is talking about of course. Naturally, I sent her birthday message to her in code.
