Roo absolutely loves her. To the point where she would hold her hand but not mine when we're walking from a park to our cars. Roo shares her snack with her (actually hand feed cheerios to her) and gives the warmest, most affectionate hugs to her.
Roo gains so much confidence being "her" when she spends the afternoon with this awesome twins. She wants to walk on her own..., brush her teeth by herself and choose what she wants to eat.
I suppose that's what a good friendship is all about... even at this young age.
