Transformers, Power Rangers, and Blue

My pink, princess-loving girl has made a 180 degree turn. Adilyn who would cry when I gave her an orange cup because it was a "boy color" now says her favorite color is blue. The girl who always wanted to watch girl shows about ponies, princess, and girlie things now chooses Transformers and Power Rangers. It's just so strange because it's like she is trying to prove a point that she doesn't love all things girlie, but yet she still wants to wear her pretty dresses and skirts. So confusing! I am sure it's only the beginning of trying to figure out what my girls are thinking!
