You need wire for... wiring purposes!

Carol has started a new business. She will fish with fish hooks she makes herself, from wire.

If you could give her an actual hook she would give you the wire.

Didn't you have one with you? Give her the knitting hook.

You have to proof that the hook catches fish. Try to find a fish, first.

Now, show the fish to Carol. She is impressed by it.

Then, give her the hook. She gives you the wire.
