Or+should+she+not+open+the+door?

When Nora noticed the door she just thought to herself "step away Nora your just going to get yourself into trouble". And thats what she did. She stepped away and forgot that the door ever existed. But befr she can forget that the door every existed she has to problems.

Should Nora tell her mother about the door?

Or should Nora just keep it to herself?
