I'm sorry that I found this post too late to vote on it! Your story hooked me and had me throughout. I love the use of tense, the mix of past and present tense, and the POV, the way you shift from talking about Bert to letting us see through Bert when you want to build suspense and hold back certain info, like in the graveyard when you don't want us to know what grave she's seeing. Your breaking conventions to mix past and present, but it's balanced and used to create an effect; you've done it to express exactly what needs to be expressed at each moment in the story. You've broken the narrative convention by mixing past and present, but the past makes the action stronger, and the present gives us Bert's awareness of himself, which helps create the sense of displacement, of being there but not really being there, which is an awesome way to imagine what a ghost must feel!
I guess you can tell I really loved it! :)
All I thought while writing this was a sad story. Of course, death would be the best for it. I wanted him to lie himself so the readers would not recognize it. To tell you the truth I had no idea how my story ended up this way. I just focused on plot but ignored the flow. But anyway I'm happy you like it. It's fine if you're too late to vote for it. You still gave me beautiful words and as a person hoping to be an author someday means so much.
Thank you
