Because it's time to pass on her shoes that are too small.
I went through Hope's closet to gather things to pass on some things to Rosalie. I had piled all of her too small shoes on her bed. She asked why they were on her bed, and I said that they were too little for her, so it was time to give them to Rosalie. She started fussing saying they DID still fit her. She struggled to get one on her foot (picture Cinderella's step-sisters trying to get the slipper to fit!) She finally got her foot in and she said "SEE it does fit. Oooouch!" I of course ran to get my camera, and she had gathered up all of them that she could hold and was headed to put them back in her closet.
