Answer:
I sleep when you are awake, I am awake when you fall asleep. I can fly but no feathers to aid my flight. What am I?
I go from house to house a messenger small and tight. Whether it rains or snows I sleep outside at night.
I have thirteen hearts but no body or soul. What am I?
I mirror your actions.
I eat I live.I breathe I live. I drink I die.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
