She Didn't Learn This From Me, Honestly...

Caity is apparently obsessed with the numbers 6 and 9. You know what number you get when you put them next to one another, right? Great. Well, she likes to put them side by side - a lot. I found 6 and 9 stickers on our play garage in the basement, adorning adjacent windows. Then just now she insisted wearing a 6 and a 9 together on her shirt. I am puzzled and not a little disturbed by this development. What gives? I suppose 6 and 9 DO have a certain symmetry to them... perhaps that's the appeal. One hopes.
