What do Peter and Anne Frank decide they had in common?

One very important similarity that they both have and share is being Jewish and that they both hide in the Secret Annex. Another similarity that Anne and Peter share is that they get so annoyed and embarrassed of their mother's. Their mother's argue mostly every time they sit at the dining table and the two kids are just fed up and sick of it happening over and over again. But when not sitting at the table, they care a lot to their families and respect them, especially during hard times. Finally, the last thing fact that I think they have in common would probably be they both have cats, but Anne did not get to bring it in the Secret Annex.
