SteelyKid's second-grade teacher sent home a couple of books about kids dealing with the loss of beloved pets one of which, The Tenth Good Thing About Barney is surprisingly atheistic. We read them at bedtime the other night, which was a little rough.
After we finished, and moved her to her bed (when it's my turn to read to her, we do it in the master bedroom, because her bed is really uncomfortable for me), she said, sadly and quietly, "I miss Emmy."
