What are the things you hate to do in model railroading?

[ezdays]

I have another thread where you can post the things you like to do, but here, you can post the things that are your least favorite things that you do in model railroading. I have my likes and dislikes, and there are even things that I dread doing, but have to if I'm going to have a layout rather than a big diorama. What is the thing you hate to do the most, and if you have several, feel free to list them all here.
