One of the kids I babysit bought a new book, and at some point his father was writing something on top of it, leaving an impression on the cover. Upon seeing this he had a complete, utter meltdown. Clearly I'm not a good person with kids because the conversation went like this:

Kid: The cover is ruined!
Me: There's literally nothing I can do.
Kid: I want it to go away!
Me: OK.
Kid: Make it go away!
Me: I can't. Yell at your dad when he gets home, he'll apologize, and then live with it.
Kid: It'll still be there!
Me: Yep.

Earlier in the conversation I gave him solutions, like ask if his dad could do an exchange, but once he completely flipped out I couldn't really express sympathy. I don't really know what you're supposed to do in that situation, so I told him to go lie down on the couch and cry it all out if he wants. I do that sometimes when I'm upset. But that apparently made him angrier because he didn't want to admit he was crying. But seriously, I just ride that shit out, but am I supposed to do something else?
