Nothing’s Shocking … or Even Mildly Interesting, For That Matter

I have had to leave concerts for a variety of reasons. I confess, I’ve been thrown out. I’ve gotten sick. I’ve gotten bored. I’ve gotten too drunk to remember anything anyway (a sort of mental exit, I suppose).

But I have never had to leave a show due to depression. That's exactly what happened tonight.
