I guess it's to scare off vampires

Let me tell you a story.
Once upon a time, I was married to a very sweet man named Brian. (I am in fact still married to him, just for the record. But this is story time, so . . . ) Brian was very good about helping around the house, whether it was the usual chores or to clean up a mess that was made by his wife or his cats. Well, one day, a rather large bottle of garlic powder threw itself off of the kitchen counter and made a HUGE mess. In an effort to help me out, he grabbed the vacuum to clean it up. I very much appreciated his willingness to get right to the task. It was cleaned up within moments! He's a good cleaner-upper.
Fast-forward to a few days later. Again, he's being a good husband and doing chores. Having cats requires regular carpet vacuuming. So, he gets out the vacuum and gets to work. And suddenly I feel like I'm in a dark, seedy Italian restaurant. One filled with greasy guidos (and I don't mean my cat). Turns out, he had forgotten to clean out the filter in the vacuum so garlic powder was getting thrown out in to the air of our little apartment. I started the fan and hoped the Wallflower would help the smell.
It wasn't until the third or fourth time of going through this that we thought to clean the filter. Sometimes we struggle. I think we were just trying a new method of keeping the vampires away. Now that the filter is clean, we will have to come up with alternative methods for keeping the vampires out, even though the whole idea is a sick interest of mine. I realize I'm weird.
