That’s almost not fair, my answer got taken before I could even start. When I read your question, my very first thought was also “Field of Dreams” even before I read your answer. So, I'll also add my next thoughts as well.

So, the next ones that come to mind are some of Wendy’s shorts. I’d say that “In His Eyes” and “Just A Little Experiment” are probably my favorites in this category. However, I love the “Yesterday” letter series.

I love these types of stories and would love to learn of some that I haven't found yet.
