This is part of the letter Amelia Earhart wrote to her then Fiancée. I loved reading the letter. It seems extremely truthful to me. Humming someday you’ll know while typing this!
Please let us not interfere with the others' work or play, nor let the world see our private joys or disagreements. In this connection I may have to keep some place where I can go to be myself, now and then, for I cannot guarantee to endure at all times the confinements of even an attractive cage.
I must exact a cruel promise and that is you will let me go in a year if we find no happiness together.
I will try to do my best in every way and give you that part of me you know and seem to want.
A.E.
