Why had the franks been forced to go in the hideout ? How did they convert their hiding place into the most lively one ?

None-the-less, the Frank's decision to move into the annex is accelerated because Margot, a sixteen year old, was called up by the SS. They did their best to create tiny living spaces within the small annex.
