I hate doing this, especially, Government ones. Since the internet is around you should be able to fill them out online and digitally sign them. But nooooo, I had to fill out one for my retirement. You can download them and print them (at least you can print multipule copies) but, you have to fill them out by hand and mail them back signed. So, after 5 attempts with a form, I finally got it right. One mistake or typo, you have to start again, you know that otherwise, they will reject them.
What's your pet hate.
