"I have a very special e-mail account that I only use for reputable business transactions and other super important things. I work very hard at keeping it spam-free. Which has been going pretty well for almost 4 years now, which is impressive.
I recently exaplained to my girlfriend that it's a good idea to keep one (or more) junk e-mail addresses that you can use whenever you have to give your address away and you know you're going to get spammed to hell. That is how I kept my special account spam-free. I always use a junk e-mail and I never give out my special address.
For some reason, my girlfriend recently decided that it would be a good idea to use my secret business address as her junk spam e-mail address. And hilarity ensued!
Dude. It totally sucks."
