I saw a big bag of cereal at the grocery store the other day and I thought of Lena, because one day she was setting on the 2nd level of her pen with a big, black, rubber tub full of cereal she was eating with a paper cup.  So I decided to buy the cereal and bring it to the zoo the next time I went with my friend, Doris.  When we arrived, Lena was inside, and when we walked in she came running up the limb to see us.  She saw the bag of cereal and motioned for me to give it to her.  I told her that I couldn't, but that I would give it to her caretakers and they would feed it to her.  Lena got mad, looked at Doris, gave her a big, juicy kiss, and turned and looked really mean at me.  She was staring at me eye to eye, then lifted her chin and looked away in a definite snub.  She repeated this process of blowing kisses at Doris and giving me the evil eye about twelve times.  I kept telling her that I was sorry, but that I couldn't give it to her.  She didn't care; she was MAD at me!!  After we left, I found out from Chris, who is in charge of feeding her, that we aren't supposed to bring food into the zoo.  Also, even if we could, they would not be able to take the food from me and feed her right then.  The veterinarian would have to inspect it first.  So not only was it fun to watch Lena give Doris all those kisses she normally can't get and see me being snubbed over and over again, but I also learned a good lesson today.  She may not be able to talk, but she definitely gets her point across.  She has feelings just like us.
