My red paper clip

The book I'm reading is about a kid that plays a game called bigger and better. Which

Is were you trade something small for something bigger or better. When he was a kid

The game did not work for him, he gave up and now that he is an adult he is playing

The game again. He traded a red paper clip for a fish pen and then he traded the fish pen

For a door knob, an ugly door knob if you ask me.
