Mechanic<br>Eric was fascinated by his grandfather. His grandfather was a mechanic. He admired that his grandfather could fix anything that went wrong. He wanted to be able to do the same. Now Eric too is a mechanic and able to fix anything that goes wrong.
Eric saw his grandfather fix things that went wrong.
He 'admired' him, but it never says he saw him actually fix anything.  He may have just heard about it or his grandfather told him.
