R.R.
One time, I kept smelling something horrible in the kitchen. I searched through cupboards, in drawers, under the liner of the trash can. For a few days, I would search. Then, I opened the microwave, where I had heated a bowl of brocolli and forgotten about it, for about 4 days.
Another was finding a bottle with rotten milk under my sons car seat - in the car - in the middle of a Texas summer. It had been there for about a week. Oh my car smelled HORRIBLE!
