Robert Frost's earliest known correspondence: notes passed during school. This one was written in 1886, when he would have been 11 or 12.

Ah, middle school. Some things never change.

To Sabra Peabody 

Dear Sabe,

I will answer your letter to let you know that I am well and hope you are the same. About me liking Lida [Storer] better than you you are all wrong because I like you twice as much as I do her and always have thought more of you than any other girl I know of. I thought you were going to the entertainment the other night but I didn't see you there. I saw Eva Hattie and your mother there. There is no fun in getting mad every so [often so] lets see if we cant keep friends Im sure I am willing. I know I have not treated you as I ought to sometimes and sometimes I don't know wheather you are mad or not and we have gotten mad and then we would get friends again ever since Westons party when I first came here. There are not many girls that I like but when I like them I fall dead in love with them and there are not many I like just because I can have some fun with them like I can Lida but I like you because I cant help myself and when I get mad at you I feel mad at myself to.

From your loveing Rob
