I understand her fascination with the skull. I have a ram's skull, a large snapping turtle's skull, a feral cat's skull, and a dog's skull on a shelf.
I sometimes study them in wonderment, marveling that so many of the things that I experience and feel were felt in virtually the same way by each of these creatures. They experienced animal joy, hunger, pain, heat, cold, curiosity...so many things that I share with them. How different am I, really?
(On a wonderful and strange side note, a man I studied Improvisation with in Chicago, Del Close, bequeathed his skull to the Goodman Theater in Chicago for use in the performances of "Hamlet" that the theater might perform. Del was the original creative director of Saturday Night Live, and a founder of the stage art of improvisation, including stints at Second City in Chicago.
If you remember, in Hamlet, the skull of the court jester, Yorick, is unearthed, and Hamlet soliloquizes about "Alas, poor Yorick, I knew him, Horatio...."
Goodman theater accepted the donation. I have to wonder if when they use the skull, whether they will give him a credit in the playnotes?
