Tim successfully fixed up the antique chair.
Why did he fix up the chair?
Because he had extra time on his hands.
It always nice when someone can repair an antique for you. It is a good use of free time to repair broken things, especially if they mean a lot to their owners.
I feel a cute creepy kind of love for the chair and Tim fixed it in a few weeks.
I'm sure you must be grateful to Tim for fixing your chair. He seems like a nice guy.
