Answer:
I am an activity dogs are very good at when a ball is thrown.
Everyone asks for me but yet everyone hates to face me. For someone I am agony for others I am relief. Who am I?
I'm sometimes white but most often I'm black. I take you there but never bring you back.
My first is in riddle but not in little. My second is in think but not in brink. My third is in thyme but not in time. My fourth is in mother but not in brother. My last is in time but no t in climb.
Break me and I am better immediately set and harder to be broken again.
What language does a billboard speak?
