Grandma says, "Zits."

When I came to pick up Lillian from school today, she showed me this picture that she drew in Aftercare. Here's what the talking bubbles say:
GRANDMA: Zits
ME: Zits

So, the word "zits" sounds pretty close to the Russian word, "zayats," which meas "rabbit."

This is supposed to be a picture of Nana saying "rabbit" in Russian to Lillian, and Lillian saying it back.
