2. You have to battle MANY manuals, pedals, and stops
You may as well be an octopus.
3. You have to leave the house to practice
Sadly, owning your own organ isn't the simplest of things. Sure, there are electric organs, but they don't even come close to the real thing. If you do want to try buy your own, you need a serious pile of dosh...
4. You are always cold
It's Sunday morning. You're a little bit hungover. You'd like to stay in your warm bed all day. But no, you're an organist. You have to haul yourself out and run along the road to your freezing cold local church by 10am to play the same hymns as you did last week, and be confronted by old Mrs Peterson as to why you don't have a girlfriend/boyfriend yet.
Even thought everybody relies on you, you are typically stuck in a corner or at the back of your local church/village hall somewhere. You never get a chance to shine or the recognition you deserve. And people leave before you've even finished **grumble grumble**
