Following in her Brothers Foot Steps

So Lilley has learned how to ride a "big" bike with training wheels.  She is following right with what her brother did and caught on to it faster.  She loves being able to ride her bike with the big kids.  Why is it that the sec that the camera comes out she wont smile?  I just don't get it.  But she still looks really cute on that bike and with her hello kitty helmet.  Summer days are the best!!!
