I'm going to disregard grammar and spelling flaws, as it seems you have help with that already!
Overall, I think this comes across as being a little cliched. Because we don't have a thorough sense of the two characters, and the story centers on an event that is not uncommon, it doesn't have anything striking to distinguish it from other similar works. This doesn't mean that it's a bad story, of course, only that it could use a little tweaking, I think.
First, I think you could use a little more interaction--a little more character development--in the beginning. Your personalities and banter are both very charming, and if you expand on that it will make your tale more interesting. Also, I think you should work a little more on expanding your paragraphs. Right now it's very choppy feeling, because you indent after each line. It makes it seem rushed, and you can't really stop and grasp what is going on while you are reading it.
You could use a little more description as well, with more expansive terms and a more consistant tone throughout this piece.
Otherwise, I think it's a great, funny, cute little story! Well done!
