Back to comment like I said I'd be.
I enjoyed the premise for this a lot.
I'm not sure if you had a word limit or not and I know with the ultra-short stories it can be hard to do, but maybe a little more 'show' and less 'tell' would help this out a little more. Not that it's not very good as it is. Programming parents, brilliant, I'm sure every kid had a time in their lives where they wished they could do that.
Poor Mona, too.
I'm curious to know what Mona's dad was converted to. I might have missed that in-text and if I did, I'm sorry. Stacie doesn't seem like she's annoyed with Mona's changes towards adulthood enough to justify the last line in my mind, so maybe adding a line that intensifies her distaste for adulthood a little more might help?
These are just some suggestions on my part, so feel free to implement or ignore them as you will. I still think it's crummy they stopped the contest before you could finish, to me it seems you would have stood a fair chance.
