Sign

So last night I put the boys to bed and then went downstairs to work on organizing my craft closet.  Apparently while I was downstairs, the boys made a sign for their door.  They then taped the sign to their door and shut the door. 

I went to their room to find two sleeping boys together on the bottom bunk and a note that read "Dot cum un are room."  I am not sure what happened to provoke the sign, but my boys felt the need to show their independence.
