Riddle: I do not breathe, but I run and jump. I do not eat, but I swim and stretch. I do not drink, but I sleep and stand. I do not think, but I grow and play. I do not see, but you see me every day. What am I?
Riddle: I am never quite what I appear to be. Straight-forward I seem, but it's only skin deep, for mystery most often lies beneath my simple speech. Sharpen your wits, open your eyes, look beyond my exteriors, read me backward, forwards, upside down. Think critically and answer the question.
What am I?
