Oh Christmas Tree

Mummy, Mama and Grace spent a lot of time today putting up this big green tree in our living room. After the tree was standing up, Grace and Mama started hanging these things off the branches. I don't know what it's all about but it sure looks pretty. The things hanging on the tree look really interesting too but everytime I go to take one off to have a closer look, I get told "No!". I have no idea what that's all about but it's very annoying.
