She's got the Kate Hands of Enthusiasm going on here. I remember being in high school and walking by my crush and turning to my friend and becoming super-animated with my gestures so he'd think I was interesting and he'd be curious as to what I was so enthusiastic about.
Obviously that didn't work as an attention-getting strategy then, but I am reminded of it whenever I see this over the top double-handed gesticulating.
Love it CF!!
give your crush MEDiana's phone number. they'll be interested!
