Three Tear-stained Notes

I really liked the idea of this and i thought that it was paced rather well with a good surprise ending. I found that the dialogue didn't sit right for me and didn't seem as natural as it could have been. "on an isolated farm track" doesn't sound very natural to me it sounds like a description. This is really petty but i get the impression that the couple are living together in her flat when she finds him with the barmaid, but she puts a letter through his mailbox. Sorry to be so petty, but I really liked the idea it's just that these things jarred with me.
