Oboe and English horn

Was listening Secret Garden when it came to an English horn solo.

I asked my brother, "You know what is this instrument?"

"Oboe," he said.

I said, "No, this is English horn."

He gave me a confused look.

I said, "Oboe and English horn, are just like violin and viola. Similar, yet different."

He said, "o."

After some time, English horn solo again.

I asked the same stupid question again.

He said, "oboe."

I said, "No!!"

He said, "Oh, viola."

Errr..
