This was triggered by the other recent basketball thread.
20s woman is at park thinking about her life, and sees guy shooting hoops. They get into a game of Horse IIRC. Afterwards they sit and talk, and she finds out he is a senior and is trying to find a way to pay for college. They wind up having sex. Several months later he receives a forwarded letter from her. She tells him that when they met she had just found out she had incurable cancer and was at the park trying to get a handle on what was left of her life. She tells him how much shooting hoops with and after her meant to her. Enclosed is a check for him to be able to go to college.
Relatively short story but just can't come up with the right key words for search.
