THINGS MY HEATER SOUNDS LIKE

I still get scared even tho I know it just means I won't be getting frostbite tonight
  1. a really heavy door creaking open for 20 minutes straight
  2. a huge bag of marbles being tossed through a metal pipe
  3. a lil squirrel walking around on the roof
  4. a woodpecker wood pecking very lightly and in slow motion
