THAT CHEESE

I was volunteering as a presenter/observer guide during a recent chimposium. When it became time, I took a group of guests down to the observation area to view the chimpanzees in their home. When we came in, Tatu was sitting on the big tire in the West Room looking at a magazine. I noticed that she was signing CHEESE and so I told the group what she was signing. I began talking about something else in the room and soon after a guest asked me "Is this a sign?" referring to something Tatu was doing. When I looked at Tatu she had put her hands together in an approximation of CHEESE. I asked CHEESE with a raised brow to clarify. Tatu paused to look at me then flipped back through the magazine she was looking at and signed THAT CHEESE, pointing to an advertisement for a cheesy macaroni dish.
