Answer:
Die without me, never thank me. Walk right through me, never feel me. Always watching, never speaking. Always lurking, never seen. What am I?
I am an activity dogs are very good at when a ball is thrown.
I am gold and can be black and white I'm a symbol for a nation when freedom took flight.
I'll bring out your bulls and slow your roll. I may even come out of your skull.
I go around in circles, but always straight ahead, never complain, no matter where I am led.
What is always coming but never arrives?
