I just read the 3 chapters, and I enjoyed it very much.

And I agree with Rinna, you got the child-like pov spot-on. Also, simple details like, She gave me her mittens when she saw that I didn't have any. One was green, and one was yellow give the story so much life.

Oh, and some of the things A says and thinks, like how words have colors and feelings - does he have synesthesia here?
