When sadness is at your door

A lovely book to teach acceptance/diffusion. A child opens the door to sadness visiting. At first the child tries to shove it in the closet and avoid it, then "it feels like you've become sadness yourself" (the child is surrounded by sadness). The narrator reccomend giving sadness a name, asking what it needs, taking it outside, and doing some things "you both enjoy". In the final part, the sadness character turns into a blanket.
