Abigail Adams once wrote to her husband while he was part of the Continental Congress drafting the first Constitution to "remember the ladies" because most men "would be tyrants if they could." She and her husband agreed on many points, but where their ideas diverged, she had no issues with debating with her spouse.
Many of us cherish letters written by husbands and wives or their children. I treasure the poetry letters my grandmother wrote to her father and the ones he wrote back. They are a joy to read and share!
