There was a red couch , yellow chair , red table , half yellow and half red carpet . All red and yellow . I then went along and started opening doors . One door led to another red and yellow cozy looking bedroom , another had led to a red / yellow bathroom , but the last room on the first floor ( there were two ) was locked .
According to the above context, answer the following question.
What may be a plausible fact about the last room on the first floor ?


It is locked from the inside .
