Stupid me
I've been wondering why the window air conditioner sometimes emits a smell similar to the adhesive on ductape, or the adhesive on Scotch tape. Today I figured out the deep dark mystery. It's because I placed ductape around the edges of the outlet.
Apparently the ductape had become such a habitual part of the air conditioner that I stopped thinking of it as an entity which might possibly send the smell of ductape into the room when you blow air across it. You might reasonably expect ductape to smell like ductape, but this outline had apparently ceased to be ductape in my idiotic perceptual system.
(Reminds me of the old moron joke, more recently translated to a
blonde joke, about the two horses.)
The remaining mystery is why Sears built an air conditioner with an air outlet that can't be turned upward, thus requiring an outline of ductape to force the outlet into a useful position. That mystery I can't solve.
