A Gentle Tap

Um, hello? It was very shadowy and quiet around me, but then my elbow gave a little *click*. Wait, I can move! I tried lifting my hand, but bump—my fingers gently bumped the smooth, clear plastic wall right in front of my nose. Oops, clumsy me! I tapped it softly again with a fingertip. *Tap, tap.* The cool, smooth surface felt neat under my hand. I decided to stay right here, resting my palm against the clear window, watching the calm shadows outside.
