What's wrong with this picture?

It's my same Lucy-girl in both pictures.

In one she's starting Kindergarten.

In the other she's starting High School.

I can't tell which is which.

She looks exactly the same to me.

Deep breath.

Heavy sigh.

Welcome to our first day of  high school.

(I'll have this whole Kindergarten/High School thing cleared up by recess, I'm sure.  My meds will have worn off by then. =D)
