Nothing to apologize for. I actually agree with you. I don't really read horror and I've never written it. I wanted to stay out of my comfort zone a little bit longer and try a few more new things, as a "just to see if I can" sort of experiment. I've noticed a lot of horror endings tend to leave you with negative feelings, a feeling of bitterness or loss, or frustration over a lack of real resolution. It was actually hard for me not to elaborate on the ending. I wrote out what he actually said to her several times before ultimately deleting it. This story was also based off of a dream a friend of mine told me about having, and I ultimately concluded that being cut off just before you get the clear answer felt very dream-like. Another "deleted" alternative ending was going to be her simply failing to hear what he said before drowning. Maybe that would've been more fitting to a true horror style. Maybe a horror fan could set me straight on this.
I'm glad you accidentally read it and commented though. You helped clarify something I was already feeling.
