Why is Elizabeth so pleased with herself in The Egypt Game?

The
children haven't been able to play the
Egypt Game for some time. When they finally start playing
it again, they
figure that the gods must be mad at them for being away so long. So the kids
come
up with the idea of performing a sacrifice to the gods. In Ancient
Egypt, it was common to make
such sacrifices as a way of appeasing the gods'
anger. Of course, the children aren't about to
do anything gruesome like
sacrificing animals or humans, but they do at least want to make their

sacrifice look realistic.

It's then that Elizabeth makes an
unusual
suggestion. She says that the kids should prick their fingers and
then write a letter to the
gods in their own blood. This will be a way of
apologizing to the gods for being away from the
Egypt Game for so long. As it
will involve the children's own blood, albeit in minute
quantities, there'll
be an element ofabout it, as the shedding of blood was an intrinsic part of

sacrifices in Ancient Egypt.

The other children think that
Elizabeth's idea
is really cool. Not surprisingly, Elizabeth is rather
pleased with herself for having come up
with such a popular
idea.
