run.

Girl:

 I wrote him a letter today. It was only a few sentences,
but it summed up everything that I felt about him and our relationship.
I kissed it and dropped it in his mailbox, then left.
I took the next train south and never dared to look back.

Boy:

 I grabbed the letter from my mailbox.
It had my name on it, written in her loopy handwriting.
I opened and read the four sentences.
I dropped the letter in the garbage, laced up my sneakers & started running.
