Communication... Is it a hard thing to do?

I don't understand why it is so hard to string a few words together and make a coherent sentence. In fact, said with enough confidence, even completely random words put together can almost sound like they make sense. Let's try it.

The box ran awkwardly and covered itself in light.

See, doesn't make much sense, but better than saying:

T-t-th-th-the b-b-bb-b-ox rrrran aw-wkwa-ward-wardly and and and cov-over-overed itsel-self in light.

I can see the difference, can you?
