Hiding Place

Yesterday, I ran away from home. I no longer felt welcome there. So, I commenced to roam. Where am I? No one knows where! I've had lots of hiding places - like inside a barrel of wine. I make sure to leave no traces - That aftertaste ain't mine. One day, I hid behind your couch. You didn't know I was there, and once inside a roo's pouch 'til I bounced out in the air I've been to every place and land, Traveling mostly by balloon. Once, I decided to expand, and I sailed up to the moon. But, I am getting lonely, see - because I'm so good at hiding. So, I will tell you secretly the tricky place I'm residing. Yesterday, I ran away from home Guess what - I'm hiding in this poem.
