Expectation

Remember that time when you were a kid, and you made the mistake of biting into a block of baker's chocolate?

The good news is, it wasn't just you. A lot of other people did it.* It looked like chocolate, it smelled like chocolate, it was even in a package that clearly said "chocolate." How were we to know? I mean sure, our moms told us not to eat it, but they said that about lots of candy. The only clear road available was trial-and-horrible-horrible error.

So where's that warning label, huh? Where was Mr. Yuk? I know he's got more important things on his plate, what with keeping people from ingesting deadly poisons, but come on! Take five minutes to say "Listen kid, I know all the experiences in your short life say that this package contains pure, sweet deliciousness. It doesn't. Contained beyond this warning is bitterness distilled, its textural similarity to proper chocolate only highlighting its terrible shortcomings. You'd be better off chewing an unground coffee bean. Walk away."

*In fact, consider yourself lucky. For some people it was unsweetened cocoa powder.
