Can you keep a secret?

It was...strange to say the least. The only Halloween store in town closed early on Halloween nights? I never understood why, that is until I needed to get a mask and rushed over to the store hoping it was open. Alas it was not and when I knocked on the door no one answered, so I made my way around the side of the shop where I heard faint music to peek through a window when I saw it. There in the center of the room metal arms holding one hand and one hip so delicately, was the shop owner and the suit of armor she had gotten shipped in but never sold two Halloweens ago. I watched as they danced and swayed to the sound of a soft piano and the warm atmosphere reached me through the window. I never spoke of what I saw at the Halloween store that night, not even to the shop keeper so this'll probably be the only record of this even ever happening. So....Can you keep a secret?
