Passenger Side Door

Barb left me a to-do list when she went to the US Open.  One of the things she wanted me to do was change the furnace filter.  I went out to buy a replacement filter at Home Depot and I decided for some reason to put the filter on the passenger seat by going around to the passenger side of the car and opening the passenger door.  I never go around to the passenger side of the car and Barb never rides in the Nissan because she hates the colour of it.  So no one ever gets into the passenger seat and no one ever goes to the passenger side of the car.  When I went to put the filter on the passenger seat and walked around the car, I saw a giant bird poop on the back passenger door near the handle.  There was no bird poop on the window.  So I never would have seen the bird poop unless I had bought a furnace filter and decided to put it on the passenger seat through the passenger door.  So I had another thing for my to-do list.  Clean the bird poop off the Nissan passenger door.
