Let them eat cake

Think of what your favorite dessert is. Mine would definitely be a chocolate shake or chocolate chip cookies. But for the sake of this story I will stick with cake, mainly because shakes and cookies are hard to compare. And because this story really is about cake, there is nothing underlying.

You walk into a bakery but don't really want anything. You are browsing because you have the time but don't care to eat, your stomach is full of wholesome things, not stupid cake. As you are there you see someone making red velvet batter so you think maybe you could use a little dessert to top off all the healthful things you have eaten. The person making the cake approaches you and explains to you a little bit of how the cake is made and says "ya know, if you want some you might be able to have some but I'm not really sure because there are a lot of other people that want it too, and one cake can only go so far."
After a lot of back and forth you are finally able to try some batter and it is pretty good, you can only imagine what it would taste like after it was actually baked. So you taste this batter and the person making it knows that you would definitely want some of the cake after it's made the only problem is that if you try a piece, you'll want the whole thing. The baker tells you that you could try a bite when it's ready so you sit down, get out a plate and a fork and as soon as you do that, the baker realizes that you're too ready and won't be satisfied with just a bite, you'll want a whole piece and then you'll want the whole cake. The baker starts talking about the other people that want the cake and that you're not the top priority at this point. So after a little hesitancy, you put the plate and fork away and accept that you just won't have any cake today and you sheepishly walk back to the table you were sitting at.
As soon as you sit down someone puts a piece of yellow cake with chocolate icing in front of you and says that if you like it, you can have the whole cake. No questions. Other people have tried it and liked it, but the whole cake is yours for the taking if you want it. Easy as that. At this point the person making the red velvet cake realizes what is happening and becomes concerned because everyone wants a slice of what they are making. It's not the fact that they want to share the cake with you, it's the fact that someone else can come along with a cake that required little effort to make and yet it still tastes just as good.
So the red velvet baker has to act fast and they open the oven just enough for you to smell the cake and be reminded of what you originally wanted. The cake is almost ready and you start to slow down on the yellow cake just in case they decide to share the red velvet. The only problem is that you know that you can have the whole yellow cake and you're still unsure as to how much red velvet cake you really would get. So you begin to debate with yourself. Red velvet was the original and you know that you would like it but yellow cake tastes just as good, it just wasn't what you were craving. But you know that if you take the yellow you get it all. If you go for the red the baker is prone to changing their mind and might only let you have a piece, leaving you cakeless and craving something that you never needed in the first place.

The moral of the story is that the world is a cruel place and you are never allowed to just have your cake, and eat it too.
