Christma Spirit

Where has all the Christmas spirit gone to this year? For whatever reason I can't seem to get into the Christmas spirit this year and it kinda seems like everyone around has been struggling too. Could it be that I feel like it just snuck up on me? Could it be that I don't have a Christmas tree at my house? Could it be that I think its all too commercialized now? I am not sure what it is but I wish I knew and I wish I could get into the spirit.
