What's wrong with these 2 pictures?

For all the mystery fanboys: Now what's wrong wit these 2 pictures?

Yes, in one picture there's a string missing.

And yes, in the other picture there's a package with a string missing. Guitars usually happen to have 6 strings.

The story behind it is the following:

Daniel must have been a little bit brutal with his guitar and broke a string. "Let's change it" he thought and took the spare set of strings he bought a couple of days ago. As he opened it, he discovered that one string was missing.

You know what's coming, don't you? Yes you do.

The one string he needed was nowhere to be found. Someone must have stolen it from the shop he bought it in.

Which leads us to the moral of the story:

God is a sadist.

You've heard it here first...
