Oh, this is absolutely gorgeous, and all kinds of heartbreaking. I really liked the second person - it works well for this piece. Way too many favorite lines to quote them all, but this?

and the doll.... it could never love you, no matter how much you loved it. It could only grow old and fade.

...made me die a little inside. The whole piece was like that, actually - beautiful and melancholy but not at all overdone. I adore Jeff/Chip and they don't get nearly enough love in the fandom. You've got me tempted to take another stab at this pairing, between this story and Dyatlov Pass (which I was just revisiting and found this story after clicking your author tag).

Very, very nicely done.
