Well, if I had to decide, I would say neither. For one thing, they are both way too long, You are going to have peoples' attention for about an hour with these stories. These are not 'short' stories, as far as I'm concerned. For another thing, there is no real payoff. It doesn't get me thinking, it doesn't get me worked up. I read these stories and feel empty. I feel like my time has been wasted.
That is my honest opinion. if you try to read these in an open forum, you will bore people.
Don't be discouraged though. I'll tell you what your problem is. Write poetry. Don't write stories.
Write something short and sweet. These are not good stories, but they are good (though incredibly long and drawn out) poems.
Get out a single A4 piece of paper, and rewrite one of these stories (probably the Tuesday one) onto it, on only one side, in your usual handwriting, including the start middle and end.
Once you've done that, take that piece of paper to your open mike night and read from it. That's my opinion.
