Just out of curiosity, how is your friendship faring now? Does she still talk to you after all of this? If she was so shallow as to not think of your time and what effort goes into a cake of that magnitude, not to mention waiting until the absolute last minute to try and order a cake for her own child at such a late hour, then I would think that she would be blaming you for the party being a "bust" due to not having a themed cake.... If that IS the case, my suggestion would be that the next time you have a cake to make for an event, make sure you keep all of the receipts for ingredients(as well as price out what you already have on hand- ya know, 90 cents for a tsp of extract, etc.- and show it to her) THEN add in the hours of prep work, baking, cooling, torting, etc. and SHOW her THAT so that she gets a clear picture of what it was that she was asking of you, and what type of challenge that you ACCEPTED because you care about her as a friend. Then, maybe next time, she wont be as self absorbed as to EVER make a request like that to ANYONE, not to mention you...
