How did Anne's feelings for Peter affect her realtionships with the others in the Secret Annexe? How did their surroundings affect Anne and Peter's relastionship?

Peter provides a sort of coming of age for Anne. Like most teenagers her interest n Peter cause her to distance herself from her family. When Anne and peter visit each other, they must endure endless chatter about their relationship,

“We don’t take much notice of all this parental chatter, their remarks are so feeble. Have the two sets of parents forgotten their own youth? It seems like it, at least they seem to take us seriously, if we make a joke, and laugh at us when we are serious”

Anne begins to resent her mother's interference in her relationship with Peter and appreciates her father's acceptance that she is growing up.
