Short Stories with Tragic Endings

I am at my house and my Dad is apparently running some sort of lemonade stand, but
there's no stand. He has this lemonade but he has very poor business skills. He knows
all about Sales / Supply & Demand, but he doesn't have a good relationship with his
customers. He tends to fight with them a lot. We are on the roof of my house for some
reason and we have a black tarp over the front lip where we are sitting. We are working
on something when my dad asks if I am able to get down from this height. I look, It is
a decent fall but not too far so I say yes. I jump down and fall promptly to the ground and
land gracefully. In real life, I probably would have hurt myself. I go into the garage and
start talking to a friend about my dad's customer relation issues and come up with the idea
that I should start a better "company". Somehow, computer programming plays into it and
we talk about that for a while. For some reason, I'm a better programmer ( not true in
waking life ) and the friend asks me a questions like "Do you know Emacs Lisp?" Or something
like that. I tell him I do not, but I'm going to learn it. By this time we are in a huge warehouse-
like place. Almost like an aircraft hangar. The dream ends.
