Squatters in my house waking me up!

I wake up at midnight to this really strong smell. I have this vague recollection from a novel I read upteen years ago about someone smelling a strong pungent smell before dying. Yikes! Isn’t it crazy what pops into your head randomly? I know it’s midnight because I groped along the night stand to find my cell phone and held it two inches from my eyeball. Stinkin’ nearsightedness. Anyway, I still hear the moose calls emitted from Chuck next to me so I figure I’m not dying, just over-whelmed with this smell that’s a cross between the first air blown out by the furnace in the fall, and mangoes. I can see light from the hall and I want water. I get up and do my 45-year-old lady shuffle in the middle of the night towards the kitchen. Isaiah is in there spreading peanut butter on a slice of my home-made wheat bread. “What is that smell?” I croak out. (At this point I’d been asleep for two and half hours. Hey, I need my beauty sleep- besides, I’m a morning person.) He just says, “I don’t know; g’night momma.” and heads to his room. I pour filtered water from the pitcher, trying not to spill with my half-asleep motor skills and shuffle back towards the smell coming from the “kids’ bathroom”. Obviously Bath-n-Body has some new scent that is not going to be my new favorite, and Chris has used the entire line of products in one fell swoop.
