“Why”? What kind of question is “why”?

This is the spirit I come to HN for. Thank you for sharing.

The most frightening realization hit me: there wasn't any reason behind what I'd done. I mean, I knew why I'd done it - I just did it because it would be fun. But I knew they would ask, "Why the hell did you do this?" and if I didn't have a good enough reason, they would probably throw me into a mental institution." -- Boyd Rice
