How do they learn that?

I have been trying to take it easy so that my round ligament pain will heal up, so I was sitting at the computer and Saphrin had been asking for something to eat. Well she didn't eat her lunch (it was still on the table) so I said there is your lunch go eat it. Well I guess she doesn't really like scrambled eggs. She was saying I want this and I that and I kept telling her NO your lunch is on the table, so she said that she wanted M&M's...I said no again. Well she opened them. I told her to put them on the counter. She did. She came out and watched some cartoons. Then she went back in and got her blanket. It was all balled up when she came out to the living room. She sat in her chair and was so quiet. I was amazed. After a couple minutes I looked over at her and noticed that she was eating something. I got up and went over to her... she was eating those darn M&M's. I couldn't believe that she hid them from me successfully. She is hitting a whole other learn of person. I was shocked to say the least. I guess I have to watch her a little closer now. UGH!!!
