I would even store my drinks in there because she would snag those from the kitchen fridge as well.  In this one area I have a leg up on her. When I drink soda I drink diet soda. She won't touch the stuff because artificial sweeteners are the devil and it's all I buy. I have a Brita filter water pitcher that I use for drinking water but she doesn't think the Brita filter is good enough so she will only drink bottled water. I don't even try to explain to her that the water she is drinking from that plastic bottle has been filtered the same way.... may as well bang my head on a brick wall.  She also believe vaccines cause autism. =)  I don't think she would go into my room while I'm away but I know of ways to lay traps so I can determine if she has. And I will. If I determine that she has I will go buy a new lock set for my room with a key that only I have.
