ballet shoes

In my investigation to learn more about little girls wearing pink, I met Nina, an imaginative 6yo Dutch little girl. She told me a story about pink ballet shoes eating strawberry icecream. Nina:
Two ballet shoes meet on the grass. One says "hello, you're very beautiful and pink". The other one says "but you're pink too ; maybe we're sisters".
They then start walking together and get a pink strawberry ice cream.
