Of all the habits for a ghost to have

I was sitting in my living room the other night, watching Bones, of course, when I was overtaken by an odor. The front door and windows were closed.

Suddenly, my house smelled like pot.

I'm certain that at some point in the past, I have ranted about how much I dislike the drug and the smell of the drug and anything that has to do with the drug.

You can speak to me all day long of medicinal properties, and while I will admit there likely are many, I still don't like it. Yuo aren't going to change my mind. This is a lifelong hatred with many levels of reasoning behind it and quite frankly, I don't think I need to fix it, I'm fine with hating pot.

I went outside, and sure enough, there was an odor out there too, so it's very likely that the smell came in through the back door, which is actually close to the front of my house.

Which means that either someone was smoking pot close enough to my house that I could smell it at my front and back doors and along the path in between (without me hearing footsteps or alerting the dog) OR my ghost has a very unwelcome habit.
