personally i think that if anyone in real life actually anciently a bird with a door the goes off campus then gets on campus then writes a note that Sammy accidentally slept in and woke up late.  i think at least someone would actually well see here like maybe someone walking down the street or one of the sectary's or teachers.  well yeah it could happen anybody can walk off campus like i can at my school no one is watching us.  but still anyway i think so far in the book its kinda interesting someone opening the cage hiding in a closest why was there another teacher stealing from Mrs.Amber.  but if Mrs.Amber ever did find out how much trouble would sammy be in i would like to know alot.
