Overheard at a church: "I don't like to complain, but..."

Here's a little quiz. What was the topic of Sunday's sermon? Its application? The Bible passage from which it was preached?

I know, it's Wednesday. Maybe this quiz would've been easier on Sunday afternoon.
Maybe.

Why is it so easy to remember the mistake the pianist made, or the fact that the guitar player didn't smile or sing along on any of the songs, or the lady, one pew back, who should've stayed at home with her cough, or even the pastor's argyle socks? (Not that there's anything wrong with argyle socks.)
I'm posing these questions as rhetorical.

And the quiz is optional.
