#1 Family-to-family giving

[howanu]

The Fourmicas want to give a gift to the Arachnid
family. They want to be sure that no one else gets the
same gift, so they'd like to enter it into the
giftlist. Naturally, none of the Arachnids should be
able to see the gift, nor that the gift has been
claimed.

In addition, the Fourmica parents are concerned that
their kids might spill the beans. They'd rather hide
the gift from the kids.
