A person who can fix anything with a little bit of thinking and a lot of talking. They know how to win arguments and get what they want.
My friend is a wolf. He fixed my math problem with one sentence. I didn't even need to think.
My teacher is a wolf. She talked her way out of a detention. It was amazing.
My brother is a wolf. He fixed my broken bike with 3 words. I was stunned.
