This sounds like the start of a really good start to a good story... It hooked me right away and when I got to the end I wanted to know more. Hope you continue to add to this. So far I have really like everything I have read that you've wrote. Keep up the good writing...
Oh, my golly!!! That was a really, really good story. Just how you described the chocolate cupcake was beyond perfect-- I could practically taste it. By the end not only did I want my own chocolate cupcake but I wanted to know more... This was a perfect short story and I think you could even take it further if you wanted and it would still be magnificent. Great job! Keep up the good work.
