What type of letter did Abigail Adams write to her daughter?

Her letters were about many things. Since John Adams was away a great deal she wrote about the farm, her observations of the war ( she could see the Battle of Bunker Hill from the farm), the children ( they had 6 ), her thoughts about the revolution, the shortages they suffered because of the war, and her fears about the British showing up at the farm. She once asked him what she should do if the British did raid the area. He told her to take the children and hide in the woods. She also wrote to him about women's rights and how she thought the country should be organized. They were married over 50 years so her letter reflect her love, worries, and thoughts.
