I read the whole thing and even tried to come up with a finsihing sentence, but I'm struggling.

You see, the story has a pefectly fine finishing sentence..."...2 large rips from my bubbler sitting back wondering what this day had in store for me"<----that, I think IS the finishing sentence. If you would have left that last part out, then we could use anything to fnish the story, but you finished it for us.

That's how I saw it anyways. Trying to add a last sentence to that would just seem out of place.
