It's a battle

Some people view organ recitals as the battle between the performer and the audience.

If you play for to long, the people who listen to you, will start to get bored.

And if they get bored, your communication and art isn't going to have an impact you seek.

If there is no positive impact, they will not show up to listen to you again next time, they will not tell their friends (except maybe about how bored they were). You don't want that to happen.

We all are walking on the edge of the sharp knife here.

In the end your audience always wins. I've seen this happen more times than I wished. It wasn't pretty.

Get out of there before it's too late.
