getting ready for christmas

This is the first year that Lauren gets to have her own tree in her room. She was very excited about it. I made the mistake of telling her at night when she went to sleep we had to turn it off. And because she has to ask "why" to everything. She asked why we had to turn it off so I said if we leave it on it could start a fire.....don't know what I was thinking. She freaked out and now we never turn the tree on.
