When I picked Emmy up today from school, her teacher helped her into the car. The teacher approached with a huge grin. This is how the conversation went.
Ms. J: Congratulations!
Me: Thanks. -- Wait, what?!
Ms. J: I hear there's a new addition to the family on its way.
Me: To my family?
Ms. J: Yes. Emmy told us that you guys are having a little girl and naming her Katie.
[at this point, Emmy is ducking into the backseat and avoiding eye contact with either of us.]
Me: Wow, that is exciting. Even I wasn't even aware of it.
You must know I'm about to give you the next obvious conversation - between Emmy and myself on the drive home.
Me: Emmy, why did you tell Ms. J that?
Emmy: Because I thought it would be a funny story to tell.
Me: Did you know that was like lying.
Emmy: No. It's just a funny story.
Me: It's only a funny story if you say 'just kidding' at the end so they know your not telling the truth.
While this was an awkward situation for everyone (I'm obviously not doing well on this diet thing if I look far enough along to know the gender of my unborn fetus) I realized this evening that I taught Emmy that she can say pretty much anything, stick a "JK" at the end of it, and get away with it.
Glean what you will.
