String Pull

I saw two strings hanging down by the window! They had little plastic bells on the bottom! So I grabbed both strings in my fists and yanked as hard as I could! THWACK! Uh! The white slats up top snapped shut and clattered like crazy teeth! Clack-clack-clack-clack! Then I let one go and yanked the other one sideways! The whole blind went crooked, like one side was sleeping and the other side was awake! I jumped up and down and yanked again! Best noise ever!
