Are All Temptations Actually Sins?

Mother continues to read from The Catholic Mother and The Catholic Father, and answers questions from: Anonymous, who struggles with scrupulosity and asks if all temptations are sins;  Grace, who wonders why Our Lord seemed to rebuke His Mother;  Hannah, who wants to know the difference between a nun and a sister;  Jeanie, who has trouble with her Protestant relatives regarding conversion of the Jews;  Richard, who asks whether God answers non-Catholics' prayers;  And Kristen, who wants to encourage her husband to lead family prayers more often.
